Product Plesk Obsidian
Version 18.0.23 Update #3
PROBLEM DESCRIPTION
Plesk sends certain system notifications out to customers, depending on settings under tools & settings, notification.
Since enabling email security, those mails are not being delivered, but bounce back with an error message:
subject:
Undeliverable mail, invalid header section
This nondelivery report was generated by the program amavisd-new at host

INVALID HEADER
Duplicate header field: "Content-Type"
Return-Path: <[email protected]> (OK)
From: Server Admin <[email protected]> (dkim:AUTHOR)
Message-ID: <[email protected]>
X-Mailer: =?UTF-8?Q?PHP/7.3.13?=
Subject: Application Updates.
STEPS TO REPRODUCE
enable a few notifications to customers. Wait for the notifications to be sent.
for example: application updates, or lets encypt can't issue, or the like.
ACTUAL RESULT
mail can't be delivered but bounces back. see above
EXPECTED RESULT
notification mail is being delivered.
ANY ADDITIONAL INFORMATION
unlike how it should have been done (remove magicspam first), email security was installed first, than magicspam was removed. the magicspam version was a leftover free version rom the Onyx days.
in case it helps pin down the cause of the issue.
YOUR EXPECTATIONS FROM PLESK SERVICE TEAM
