Hi Everyone! a problem started today. Running iRedMail on Ubuntu 16.04.2
We are no longer receiving emails inbound, or they are very rare. I see a message in logs now. Apr 10 23:35:20 mx postfix/postscreen[14708]: CONNECT from [49.0.12.212]:11528 to [10.200.XX.XXX]:25 Apr 10 23:35:20 mx postfix/postscreen[14708]: PASS OLD [49.0.12.212]:11528 Apr 10 23:35:20 mx postfix/smtpd[14732]: connect from smtp2-1.nbnco.com.au [49.0.12.212] Apr 10 23:35:20 mx postfix/smtpd[14732]: Anonymous TLS connection established from smtp2-1.nbnco.com.au[49.0.12.212]: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) Apr 10 23:35:20 mx postfix/smtpd[14732]: NOQUEUE: reject: RCPT from smtp2-1.nbnco.com.au[49.0.12.212]: 451 4.7.1 <simon.sedgw...@xband.com.au>: Recipient address rejected: Intentional policy rejection, please try again later; from=<prvs=266c32978=contractmana...@nbnco.com.au> to=< simon.sedgw...@xband.com.au> proto=ESMTP helo=<smtp2-1.nbnco.net.au> Apr 10 23:35:25 mx postfix/smtpd[14732]: disconnect from smtp2-1.nbnco.com.au[49.0.12.212] ehlo=2 starttls=1 mail=1 rcpt=0/1 rset=1 quit=1 commands=6/7 Maybe conincidence, but an old test server was started earlier today, I can see connection attempts from it. though this box is now repurposed and fully rebuilt.
