I've configured PostFix as a null client on my machine as it's said here.

But some mail got bounced. I checked log and found there, that "from" values equal script username on the machine, not email address in the email:

Emails got bounced like this:

How do I setup postfix correctly?

Email is sent by php scripts using "sendmail" binary (postfix replacement of it).

PostFix configuration:

[root@server2 log]# postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
debug_peer_level = 2
debug_peer_list =
html_directory = no
inet_interfaces = loopback-only
local_transport = error:local delivery is disabled
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases.postfix
readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
sample_directory = /usr/share/doc/postfix-2.3.3/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
unknown_local_recipient_reject_code = 550

Please show output of postconf -n. – AlexD Apr 25 '11 at 14:14
@AlexD done. Thanks in advance. – Vladislav Rastrusny Apr 25 '11 at 16:42

To set From: e-mail address you need to use -f option for sendmail binary.

Second bounce probably caused by relay_host pointing to server ( which doesn't relay mail for your server.

Sometimes I cannot use -f everywhere. And does it really affect STMP MAIL FROM command? relayhost is commented in config file. – Vladislav Rastrusny Apr 25 '11 at 16:40
