Hi!
I've just installed a new mailserver with Postfix, MySQL, Dovecot and Maia-Mailguard.
I'm also gonna use this server as a "relay" for other servers so their mail gets spam/virus checked om my server and then over to the mailserver with the accounts on it.
Code:
DNS example.com -> 192.168.0.1 (to my server, spamcheck)
DNS smtp.example.com -> 192.168.0.2 (mailserver, where the mail ends up)
Mail to example.com --> my server, get spamchecked, send to --> smtp.example.com
If you understand what I mean!?
Anyway, I put this in /etc/postfix/transport:
Code:
example.com smtp:[smtp.example.com]
and run
And I get this in the log:
Code:
Feb 11 11:49:38 example.com postfix/smtpd[24775]: NOQUEUE: reject: RCPT from blu0-omc2-s8.blu0.hotmail.com[65.55.111.83]: 550 5.1.1 <test@example.com>: Recipient address rejected: User unknown in virtual mailbox table; from=<test@hotmail.com> to=<test@example.com> proto=ESMTP helo=<blu0-omc2-s8.blu0.hotmail.com>
So it checks my database if the
test@example.com exists, which it doesn't because its on smtp.example.com where its suppose to deliver to when its checked for spam.
So how/can I do so if the domain exists in transport-file, it doesn't check the database if the user exists and just process the mail and send it away?
My /etc/postfix/main.cf looks like this:
Code:
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no
append_dot_mydomain = no
#delay_warning_time = 4h
myhostname = mail.example.com
myorigin = example.com
mydestination = localhost
relayhost =

# Maia-Mailguard

I really need help here so I appreciate any response.
Thanks!
Edit:
I might have to say that my server is a pop3/imap server too, so I already have email accounts on it but I also want so other servers can use it as a spamcheck server.
