Currently incoming mails from certain domains got stuck in the SPF milter check.
This happened suddenly, we are running this Plesk mail setup for over 3 years now.
The maillog shows this:
example 1 (google):
postfix/cleanup[22036]: warning: milter inet:127.0.0.1:12768: can't read SMFIC_BODYEOB reply packet header: Connection timed out
postfix/cleanup[22036]: 2535D40926: milter-reject: END-OF-MESSAGE from mail-lf1-f50.google.com[209.85.167.50]: 4.7.1 Service unavailable - try again later; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail-lf1-f50.google.com>
example 2 (microsoft):
postfix/cleanup[23472]: warning: milter inet:127.0.0.1:12768: can't read SMFIC_BODYEOB reply packet header: Connection timed out
postfix/cleanup[23472]: 577F7407F0: milter-reject: END-OF-MESSAGE from mail-dbaeur03on2105.outbound.protection.outlook.com[40.107.104.105]: 4.7.1 Service unavailable - try again later; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<EUR03-DBA-obe.outbound.protection.outlook.com>
Disabling SPF in Plesk on incoming mails solves the problem for now, these mails end up in the mailbox after disabling.
Increasing the timeouts is not a possibility / real solution.
Anyone has seen this or can think of a possible solution?
