Odp: Re: status=bounced (mail for ... loops back to myself)
OK thanks for sharing your experience I'll be changing configurations Hello. I would also recommend having unique hostnames as well, so that postfix can keep track. It's perfectly fine to have the same IP. IE: mail.mydomain.com, mail2.mydomain.com etc Also, it might not be necessary to have two instances, you can probably do it with one, as SMTPD is for incoming and SMTP is for outbound in master.cf You can specify customer ports in master.cf as well, for example, I have: My default inbound which has amavis filtering, and I have a second listener on 127.0.0.2 for internal relay mail. smtpinet n - n - 25 smtpd -o content_filter=smtp-amavis:[127.0.0.1]:10024 127.0.0.2:25 inet n- n - 25 smtpd -o smtp_bind_address=$smtp_bind_override michalr0 wrote: Hello i have two instance of postfix one for incoming (p:25) and one for outgoing (p:587) I use this configuration because in this way i may check DNS and MX records.

Hello. I would also recommend having unique hostnames as well, so that postfix can keep track. It's perfectly fine to have the same IP. IE: mail.mydomain.com, mail2.mydomain.com etc This working great, two different hostnames solves the problem solution of one instance seems to be much better Also, it might not be necessary to have two instances, you can probably do it with one, as SMTPD is for incoming and SMTP is for outbound in master.cf You can specify customer ports in master.cf as well, for example, I have: My default inbound which has amavis filtering, and I have a second listener on 127.0.0.2 for internal relay mail. smtpinet n - n - 25 smtpd -o content_filter=smtp-amavis:[127.0.0.1]:10024 127.0.0.2:25 inet n- n - 25 smtpd -o smtp_bind_address=$smtp_bind_override In this part I don't have any changes to better for test I disable auth master.cf #smtp inetn - n - - smtpd 1.2.3.4:smtp inet n - n - - smtpd -o myhostname=xxx.domain.cc 1.2.3.4:587 inet n - - - - smtpd -o smtpd_client_restrictions=permit when I added the virtual domain to such tests (gmail.com, facebook.com) e-mails reach out locally rather than according to MX records

Re: status=bounced (mail for ... loops back to myself)
Hello, mail.mydomain.dd[6.7.8.9] is the machine running your two instances? Looks like your outgoing postfix himself thinks, he is the one for domain mydomain.dd. Maybe you could give him a transport-table entry like : mydomain.dd smtp:[1.2.3.4]:25 (Remember to run postmap) If that doesn't help, please send master.cf and main.cf of both instances.
