status=bounced (mail for ... loops back to myself)
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. I have some virtual domains. When I send email to client which changing mail server (from me to other ISP) I sending emails to me server (old) not to new server and I have one trouble when I sended email from my server to outside server i working great when I received mail from outside server is working great but when i sended from me to me I have many errors NOQUEUE: reject_warning: RCPT from 1-2-3-4.dynamic.xx[1.2.3.4]: 450 4.1.7 ad...@mydomain.dd: Sender address rejected: unverified address: mail for mydomain.dd loops back to myself; from=ad...@mydomain.dd to=t...@mydomain.dd proto=ESMTP helo=[192.168.1.140] Aug 2 13:20:46 node1 postfix-out/smtp[13651]: warning: host mail.mydomain.dd[6.7.8.9]:25 greeted me with my own hostname node25.myserver.ss Aug 2 13:20:46 node1 postfix-out/smtp[13651]: warning: host mail.mydomain.dd[6.7.8.9]:25 replied to HELO/EHLO with my own hostname node25.myserver.ss Aug 2 13:20:46 node1 postfix-out/smtp[13651]: 351E9406A0: to=ad...@mydomain.dd, relay=mail.mydomain.dd[6.7.8.9]:25, delay=0.08, delays=0/0/0.08/0, dsn=5.4.6, status=bounced (mail for mydomain.dd loops back to myself) -- from log -- Aug 2 13:20:45 node1 postfix-out/smtpd[13643]: connect from 1-2-3-4.dynamic.xx[1.2.3.4] Aug 2 13:20:46 node1 postfix-out/smtpd[13643]: NOQUEUE: reject_warning: RCPT from 1-2-3-4.dynamic.xx[1.2.3.4]: 450 4.1.7 ad...@mydomain.dd: Sender address rejected: unverified address: mail for mydomain.dd loops back to myself; from=ad...@mydomain.dd to=t...@mydomain.dd proto=ESMTP helo=[192.168.1.140] Aug 2 13:20:46 node1 postfix-out/smtpd[13643]: 18BF74067D: client=1-2-3-4.dynamic.xx[1.2.3.4], sasl_method=PLAIN, sasl_username=ad...@mydomain.dd Aug 2 13:20:46 node1 postfix-out/cleanup[13649]: 18BF74067D: message-id=55bdfcfd.7050...@mydomain.dd Aug 2 13:20:46 node1 postfix-out/qmgr[12600]: 18BF74067D: from=ad...@mydomain.dd, size=563, nrcpt=1 (queue active) Aug 2 13:20:46 node1 postfix/smtpd[13652]: connect from mail.mydomain.dd[6.7.8.9] Aug 2 13:20:46 node1 postfix-out/smtp[13651]: warning: host mail.mydomain.dd[6.7.8.9]:25 greeted me with my own hostname node25.myserver.ss Aug 2 13:20:46 node1 postfix-out/smtp[13651]: warning: host mail.mydomain.dd[6.7.8.9]:25 replied to HELO/EHLO with my own hostname node25.myserver.ss Aug 2 13:20:46 node1 postfix-out/smtp[13651]: 18BF74067D: to=t...@mydomain.dd, relay=mail.mydomain.dd[6.7.8.9]:25, delay=0.15, delays=0.07/0/0.08/0, dsn=5.4.6, status=bounced (mail for mydomain.dd loops back to myself) Aug 2 13:20:46 node1 postfix/smtpd[13652]: disconnect from mail.mydomain.dd[6.7.8.9] ehlo=1 quit=1 commands=2 Aug 2 13:20:46 node1 postfix-out/cleanup[13649]: 351E9406A0: message-id=20150802112046.351e940...@node25.myserver.ss Aug 2 13:20:46 node1 postfix-out/bounce[13654]: 18BF74067D: sender non-delivery notification: 351E9406A0 Aug 2 13:20:46 node1 postfix-out/qmgr[12600]: 351E9406A0: from=, size=2339, nrcpt=1 (queue active) Aug 2 13:20:46 node1 postfix-out/qmgr[12600]: 18BF74067D: removed Aug 2 13:20:46 node1 postfix-out/smtpd[13643]: disconnect from 1-2-3-4.dynamic.xx[1.2.3.4] ehlo=2 starttls=1 auth=1 mail=1 rcpt=1 data=1 quit=1 commands=8 Aug 2 13:20:46 node1 postfix/smtpd[13652]: connect from mail.mydomain.dd[6.7.8.9] Aug 2 13:20:46 node1 postfix-out/smtp[13651]: warning: host mail.mydomain.dd[6.7.8.9]:25 greeted me with my own hostname node25.myserver.ss Aug 2 13:20:46 node1 postfix-out/smtp[13651]: warning: host mail.mydomain.dd[6.7.8.9]:25 replied to HELO/EHLO with my own hostname node25.myserver.ss Aug 2 13:20:46 node1 postfix-out/smtp[13651]: 351E9406A0: to=ad...@mydomain.dd, relay=mail.mydomain.dd[6.7.8.9]:25, delay=0.08, delays=0/0/0.08/0, dsn=5.4.6, status=bounced (mail for mydomain.dd loops back to myself) Aug 2 13:20:46 node1 postfix/smtpd[13652]: disconnect from mail.mydomain.dd[6.7.8.9] ehlo=1 quit=1 commands=2 Aug 2 13:20:46 node1 postfix-out/qmgr[12600]: 351E9406A0: removed -- from log -- Thanks for help Michael Rybnik
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.

Re: status=bounced (mail for ... loops back to myself)
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.
