E-Mail-delivery fails
I suddenly got a problem with the milter service of plesk. When an email comes in I get the following error:
milter-reject: DATA from a10-217.smtp-out.amazonses.com[54.240.10.217]: 451 4.7.1 Service unavailable - try again later; from=<###> to=<###> proto=ESMTP helo=<a10-217.smtp-out.amazonses.com>
I looked to the following document: https://kb.plesk.com/en/120384 but that is a bit confusing because I dont know at all what this milter service does....
E-Mail-delivery fails
