multi ip and postfix

[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

Code:

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 I have:

Code:

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
