postfix - one domain on second address ip(multii ip)

[raczkowski1]

Hi

I have two ip on one server (ip1, ip2) and I want do that mails from domain aaa.net.com go out with ip2 in headers and mails from other domains go out with ip1 in headers.
How do this if is it possible?

I tried this:
/etc/postfix/master.cf

localhost:smtp  inet n - n - - smtpd
ip1:smtp inet n - n - - smtpd
ip2:smtp inet n - n - - smtpd -o myhostname=aaa.net.com

But I get error login and in logs:

postfix/smtpd[30707]: warning: SASL authentication problem: unable to open Berkeley db /etc/sasldb2: Permission denied
postfix/smtpd[30707]: warning: SASL authentication problem: unable to open Berkeley db /etc/sasldb2: Permission denied

Thanks

raczkowski1,

The lines you have posted in master.cf define separate smtpd processes listening for incoming mail, not separate relay transports. Offhand I cannot answer your question completely, but it will likely be definition or duplication of another "outbound" transport in master.cf that you will then reference in a mapfile for mail from a particular domain ala /etc/postfix/transport. I am thinking something like "sender dependent transport."

I have one domain on 3 IP (=3 servers)
and I never had to change anything related to IP in /etc/postfix/master.cf
but all my IP relevant stuff was done in
/etc/postfix/main.cf

I have 3 outbound and 2 inbound mail servers on the 3 IPs and all works fine since years
