 su, su, non ti abbattere. Litigare con i MTA fa parte delle gioie della
vita ! :->
 E non ti lamentare del Postfix, Sendmail e' molto peggio - ha solo la
fortuna che di solito arriva preconfigurato come host, non come 'mail
relay only' come il Postfix.

 Dunque, si vedono un sacco di 

Jan 31 21:23:57 debian
postfix/smtp[374]: 1E70210D05: to=<manuel@debian.debian>, 
relay=212.141.53.91[212.141.53.91], delay=2, status=sent (250
<3A40BF86008CB89A> Mail accepted)

 Questo vuol dire che il tuo Postfix sta rimandando al relay_host tutta la
tua posta interna (presumo che debian.debian sia lo hostname del tuo
PC). Quello che dovresti vedere e'

Jan 28 10:12:32 pcsash
postfix/local[1202]: 00BD42092F: to=<sb@pcsash.sash.lan>, relay=local,
delay=12, status=sent ("|/usr/bin/procmail")

 Guardando il tuo main.cf, si vede che manca un

best_mx_transport=local

 senza il quale Postfix rimbalza tutta la posta verso il relay_host via
SMTP, a meno che un 'transport' diverso non sia specificato in
transport_maps:

(sample-smtp.cf)
# The best_mx_transport parameter controls what happens when the
# local system is listed as the best MX host for a destination. By
# default, Postfix reports a "mail loops back to myself" error and
# bounces the message. Specify "best_mx_transport = local" to pass
# the mail to the local delivery agent. You can specify any transport
# that is defined in the master.cf file.
#
# best_mx_transport =

per sicurezza, digli di 'acchiappare' tutta la posta per il tuo dominio:

 mydestination = $myhostname, localhost.$mydomain, $mydomain

e di non usare il dns:

disable_dns_lookups = yes

 C'e' qualche altra cosa da sistemare - leggiti la FAQ del Postfix, in
particolare la sezione 'Example configurations', paragrafi 'Stand-alone
machine' e 'Running Postfix on a dialup machine'.
  Allego il mio main.cf, spero ti torni comodo.

 Per finire, non ti dimenticare di dire a postmaster@inwind.it che il loro
server SMTP _NON DOVREBBE_ accettare posta per un dominio inesistente
come debian.debian !!!!
 Quelle mail avrebbero dovuto rimbalzare al postmaster locale, e avresti
dovuto trovarle come bounce nella casella di posta dell'alias di root (hai
configurato /etc/postfix/aliases, VERO ? :-)

# Global Postfix configuration file. This file lists only a subset
# of all 100+ parameters. See the sample-xxx.cf files for a full list.
#
# The general format is lines with parameter = value pairs. Lines
# that begin with whitespace continue the previous line. A value can
# contain references to other $names or ${name}s.

# LOCAL PATHNAME INFORMATION
#
# The queue_directory specifies the location of the Postfix queue.
# This is also the root directory of Postfix daemons that run chrooted.
# See the files in examples/chroot-setup for setting up Postfix chroot
# environments on different UNIX systems.
#
queue_directory=/var/spool/postfix

# The command_directory parameter specifies the location of all
# postXXX commands.  The default value is $program_directory.
#

# The daemon_directory parameter specifies the location of all Postfix
# daemon programs (i.e. programs listed in the master.cf file). The
# default value is $program_directory. This directory must be owned
# by root.
#
daemon_directory=/usr/libexec/postfix

# QUEUE AND PROCESS OWNERSHIP
#
# The mail_owner parameter specifies the owner of the Postfix queue
# and of most Postfix daemon processes.  Specify the name of a user
# account THAT DOES NOT SHARE A GROUP WITH OTHER ACCOUNTS AND THAT
# OWNS NO OTHER FILES OR PROCESSES ON THE SYSTEM.  In particular,
# don't specify nobody or daemon. PLEASE USE A DEDICATED USER.
#

# The default_privs parameter specifies the default rights used by
# the local delivery agent for delivery to external file or command.
# These rights are used in the absence of a recipient user context.
# DO NOT SPECIFY A PRIVILEGED USER OR THE POSTFIX OWNER.
#
#default_privs = nobody

# INTERNET HOST AND DOMAIN NAMES
#
# The myhostname parameter specifies the internet hostname of this
# mail system. The default is to use the fully-qualified domain name
# from gethostname(). $myhostname is used as a default value for many
# other configuration parameters.
#
#myhostname = host.domain.name
#myhostname = virtual.domain.name

# The mydomain parameter specifies the local internet domain name.
# The default is to use $myhostname minus the first component.
# $mydomain is used as a default value for many other configuration
# parameters.
#
#mydomain = domain.name

# SENDING MAIL
#
# The myorigin parameter specifies the domain that locally-posted
# mail appears to come from. The default is to append $myhostname,
# which is fine for small sites.  If you run a domain with multiple
# machines, you should (1) change this to $mydomain and (2) set up
# a domain-wide alias database that aliases each user to
# user@that.users.mailhost.
#
#myorigin = $myhostname
#myorigin = $mydomain

# RECEIVING MAIL

# The inet_interfaces parameter specifies the network interface
# addresses that this mail system receives mail on.  By default,
# the software claims all active interfaces on the machine. The
# parameter also controls delivery of mail to user@[ip.address].
#
#inet_interfaces = all
#inet_interfaces = $myhostname
#inet_interfaces = $myhostname, localhost

# The mydestination parameter specifies the list of domains that this
# machine considers itself the final destination for. That does not
# include domains that are hosted on this machine. Those domains are
# specified elsewhere (see sample-virtual.cf, and sample-transport.cf).
#
# The default is $myhostname + localhost.$mydomain.  On a mail domain
# gateway, you should also include $mydomain. Do not specify the
# names of domains that this machine is backup MX host for. Specify
# those names via the relay_domains or permit_mx_backup settings for
# the SMTP server (see sample-smtpd.cf.
#
# The local machine is always the final destination for mail addressed
# to user@[the.net.work.address] of an interface that the mail system
# receives mail on (see the inet_interfaces parameter).
#
# Specify a list of host or domain names, /file/name or type:table
# patterns, separated by commas and/or whitespace. A /file/name
# pattern is replaced by its contents; a type:table is matched when
# a name matches a lookup key.  Continue long lines by starting the
# next line with whitespace.
#
# DO NOT LIST VIRTUAL DOMAINS HERE. LIST THEM IN THE VIRTUAL FILE
# INSTEAD. BE SURE TO READ THE ENTIRE VIRTUAL MANUAL PAGE.

# REJECTING UNKNOWN LOCAL USERS
#
# The local_recipient_maps parameter specifies optional lookup tables
# with all users that are local with respect to $mydestination and
# $inet_interfaces.  If this parameter is defined, then the SMTP server
# will reject mail for unknown local users.
#
# The local_recipient_maps parameter accepts tables with bare usernames
# such as unix:passwd.byname and alias maps.
#
# Beware: if the Postfix SMTP server runs chrooted, you may have to
# copy the passwd database into the jail. This is system dependent.

# FOR THIS TO WORK, DO NOT SPECIFY VIRTUAL DOMAINS IN MYDESTINATION.
# MYDESTINATION MUST LIST NON-VIRTUAL DOMAINS ONLY.

# ADDRESS REWRITING
#
# Insert text from sample-rewrite.cf if you need to do address
# masquerading.
#
# Insert text from sample-canonical.cf if you need to do address
# rewriting, or if you need username->Firstname.Lastname mapping.

# ADDRESS REDIRECTION (VIRTUAL DOMAIN)
#
# Insert text from sample-virtual.cf if you need virtual domain support.

# "USER HAS MOVED" BOUNCE MESSAGES
#
# Insert text from sample-relocated.cf if you need "user has moved"
# style bounce messages. Alternatively, you can bounce recipients
# with an SMTP server access table. See sample-smtpd.cf.

# TRANSPORT MAP
#
# Insert text from sample-transport.cf if you need explicit routing.

# ALIAS DATABASE
#
# The alias_maps parameter specifies the list of alias databases used
# by the local delivery agent. The default list is system dependent.
# On systems with NIS, the default is to search the local alias
# database, then the NIS alias database. See aliases(5) for syntax
# details.
#
# If you change the alias database, run "postalias /etc/aliases" (or
# wherever your system stores the mail alias file), or simply run
# "newaliases" to build the necessary DBM or DB file.
#
# It will take a minute or so before changes become visible.  Use
# "postfix reload" to eliminate the delay.
#
#alias_maps = dbm:/etc/aliases
alias_maps=hash:/etc/postfix/aliases
#alias_maps = hash:/etc/aliases, nis:mail.aliases
#alias_maps = netinfo:/aliases

# The alias_database parameter specifies the alias database(s) that
# are built with "newaliases" or "sendmail -bi".  This is a separate
# configuration parameter, because alias_maps (see above) may specify
# tables that are not necessarily all under control by Postfix.
#
#alias_database = dbm:/etc/aliases
#alias_database = dbm:/etc/mail/aliases
#alias_database = hash:/etc/aliases
#alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases

# ADDRESS EXTENSIONS (e.g., user+foo)
#
# The recipient_delimiter parameter specifies the separator between
# user names and address extensions (user+foo). See canonical(5),
# local(8), relocated(5) and virtual(5) for the effects this has on
# aliases, canonical, virtual, relocated and .forward file lookups.
# Basically, the software tries user+foo and .forward+foo before
# trying user and .forward.
#
# recipient_delimiter = +

# DELIVERY TO MAILBOX
#
# The home_mailbox parameter specifies the optional pathname of a
# mailbox file relative to a user's home directory. The default
# mailbox file is /var/spool/mail/user or /var/mail/user.  Specify
# "Maildir/" for qmail-style delivery (the / is required).
#
#home_mailbox = Mailbox
#home_mailbox = Maildir/

# The mail_spool_directory parameter specifies the directory where
# UNIX-style mailboxes are kept. The default setting depends on the
# system type.
#
# mail_spool_directory = /var/mail
# mail_spool_directory = /var/spool/mail

# The mailbox_command parameter specifies the optional external
# command to use instead of mailbox delivery. The command is run as
# the recipient with proper HOME, SHELL and LOGNAME environment settings.
# Exception:  delivery for root is done as $default_user.
#
# Other environment variables of interest: USER (recipient username),
# EXTENSION (address extension), DOMAIN (domain part of address),
# and LOCAL (the address localpart).
#
# Unlike other Postfix configuration parameters, the mailbox_command
# parameter is not subjected to $parameter substitutions. This is to
# make it easier to specify shell syntax (see example below).
#
# Avoid shell meta characters because they will force Postfix to run
# an expensive shell process. Procmail alone is expensive enough.
#
# IF YOU USE THIS TO DELIVER MAIL SYSTEM-WIDE, YOU MUST SET UP AN
# ALIAS THAT FORWARDS MAIL FOR ROOT TO A REAL USER.
#
mailbox_command=/usr/bin/procmail
#mailbox_command = /some/where/procmail -a "$EXTENSION"

# The mailbox_transport specifies the optional transport in master.cf
# to use after processing aliases and .forward files. This parameter
# has precedence over the mailbox_command, fallback_transport and
# luser_relay parameters.
#
#mailbox_transport = cyrus

# The fallback_transport specifies the optional transport in master.cf
# to use for recipients that are not found in the UNIX passwd database.
# This parameter has precedence over the luser_relay parameter.
#
#fallback_transport =

# The luser_relay parameter specifies an optional destination address
# for unknown recipients.  By default, mail for unknown local recipients
# is bounced.
#
# The following expansions are done on luser_relay: $user (recipient
# username), $shell (recipient shell), $home (recipient home directory),
# $recipient (full recipient address), $extension (recipient address
# extension), $domain (recipient domain), $local (entire recipient
# localpart), $recipient_delimiter. Specify ${name?value} or

# JUNK MAIL CONTROLS
#
# The controls listed here are only a very small subset. See the file
# sample-smtpd.cf for an elaborate list of anti-UCE controls.

# The header_checks parameter restricts what may appear in message
# headers. This requires that POSIX or PCRE regular expression support
# is built-in. Specify "/^header-name: stuff you do not want/ REJECT"
# in the pattern file. Patterns are case-insensitive by default. Note:
# specify only patterns ending in REJECT. Patterns ending in OK are
# mostly a waste of cycles.
#
#header_checks = regexp:/etc/postfix/filename
#header_checks = pcre:/etc/postfix/filename

# The relay_domains parameter restricts what clients this mail system
# will relay mail from, or what destinations this system will relay
# mail to.  See the smtpd_recipient_restrictions restriction in the
# file sample-smtpd.cf.
#
# By default, Postfix relays mail
# - from trusted clients whose IP address matches $mynetworks,
# - from trusted clients matching $relay_domains or subdomains thereof,
# - from untrusted clients to destinations that match $relay_domains
#   or subdomains thereof, except addresses with sender-specified routing.
# The default relay_domains value is $mydestination.
#
# In addition to the above, the Postfix SMTP server by default accepts mail
# that Postfix is final destination for:
# - destinations that match $inet_interfaces,
# - destinations that match $mydestination
# - destinations that match $virtual_maps.
# These destinations do not need to be listed in $relay_domains.
#
# Specify a list of hosts or domains, /file/name patterns or type:name
# lookup tables, separated by commas and/or whitespace.  Continue
# long lines by starting the next line with whitespace. A file name
# is replaced by its contents; a type:name table is matched when a
# (parent) domain appears as lookup key.
#
# NOTE: Postfix will not automatically forward mail for domains that
# list this system as their primary or backup MX host. See the
# permit_mx_backup restriction in the file sample-smtpd.cf.
#
#relay_domains = $mydestination

# The mynetworks parameter specifies the list of networks that are
# local to this machine.  The list is used by the anti-UCE software
# to distinguish local clients from strangers. See permit_mynetworks
# and smtpd_recipient_restrictions in the file sample-smtpd.cf file.
#
# The default is a list of all networks attached to the machine:  a
# complete class A network (X.0.0.0/8), a complete class B network
# (X.X.0.0/16), and so on. If you want stricter control, specify a
# list of network/mask patterns, where the mask specifies the number
# of bits in the network part of a host address. You can also specify
# the absolute pathname of a pattern file instead of listing the
# patterns here.
#
#mynetworks = 168.100.189.0/28, 127.0.0.0/8
#mynetworks = $config_directory/mynetworks

# SHOW SOFTWARE VERSION OR NOT
#
# The smtpd_banner parameter specifies the text that follows the 220
# status code in the SMTP greeting banner. Some people like to see
# the mail version advertised. By default, Postfix shows no version.
#
# You MUST specify the $myhostname at the start of the text. When
# the SMTP client sees its own hostname at the start of an SMTP
# greeting banner it will report a mailer loop. That's better than
# having a machine meltdown.

# PARALLEL DELIVERY TO THE SAME DESTINATION
#
# How many parallel deliveries to the same user or domain? With local
# delivery, it does not make sense to do massively parallel delivery
# to the same user, because mailbox updates must happen sequentially,
# and expensive pipelines in .forward files can cause disasters when
# too many are run at the same time. With SMTP deliveries, 10
# simultaneous connections to the same domain could be sufficient to
# raise eyebrows.

# The debug_peer_list parameter specifies an optional list of domain
