Postfix 451 4.3.5 Server configuration error
21,799
Search /etc/postfix/filtered_domains for ACCEPT
on the right-hand side. You probably meant these to be OK
, as described in Postfix documentation (man 5 access). Then
postmap /etc/postfix/filtered_domains

So I'm running mail on my VPS, using Postfix + Dovecot. I am able to send, but not all mail comes in.
Note: DOMAIN = my domain, but I blocked it for security reasons.
The case: I want to use my mail on Twitter, but the verification email never arrived. I checked the log and I found the following:
Aug 20 22:20:51 DOMAIN postfix/smtpd[32679]: warning: unknown smtpd restriction: "ACCEPT" Aug 20 22:20:51 DOMAIN postfix/smtpd[32679]: NOQUEUE: reject: RCPT from spring-chicken-ae.twitter.com[199.16.156.144]: 451 4.3.5 Server configuration error; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<spring-chicken-ae.twitter.com> Aug 20 22:20:56 DOMAIN postfix/cleanup[32684]: DE1291BFC5E: message-id=<[email protected]> Aug 20 22:20:56 DOMAIN postfix/qmgr[27377]: DE1291BFC5E: from=<[email protected]>, size=1344, nrcpt=1 (queue active) Aug 20 22:20:56 DOMAIN postfix/smtpd[32679]: disconnect from spring-chicken-ae.twitter.com[199.16.156.144] ehlo=2 starttls=1 mail=1 rcpt=0/1 quit=1 commands=5/6 Aug 20 22:20:56 DOMAIN postfix/virtual[32685]: DE1291BFC5E: to=<[email protected]>, orig_to=<postmaster>, relay=virtual, delay=0.02, delays=0.01/0/0/0, dsn=2.0.0, status=sent (delivered to maildir) Aug 20 22:20:56 DOMAIN postfix/qmgr[27377]: DE1291BFC5E: removed
