Issue Spamassassin & MTA with Mailenable

[Michael Neikes]

Sorry for a probably stupid question, but I am lost in regards of SPAM detection :-(

I do use

• Windows Server 2016
• Mailenable Enterprise Edition 10.26 and
• Plesk Obsidian Version 18.0.21 Update #5

For spam detection, I have:

• enabled in Plesk-Control Panel: Tools&Settings>E-Mail>Spam-> serverwide (checked) incl. adding Text to the subject
• in MailEnable Management>Messaging Manager>Postoffice>Domain123 settings>Features
  • "Deliver junk email to Junk E- folder" checked

Unfortunately it seems that Spamassassin is not running for every mail coming in.
If so:

• subject text is added,
• mail is moved
• header is updated with
  • X-Spam-Flag: YES
  • X-Spam-Level: ***************

On those which should be marked as Spam and are not I do see at least another entry in the header "X-ME-Content: Deliver-To=Junk", so that I did on top enabled a filter (within Mailenable) where - if this is found in the header - the Mail is marked as spam as well.

I found some articles, that MTA is scanning BEFORE Spamassassin and therefore flags arenot included in header but why isit working sometimes and sometimes not?

Other settings i am not sure/aware about if correct:

• MailEnable Servers>extensions>Message Filter>SpamAssassin>properties
  • "localhost:738" but test is failing
  • "Bypas..." is enabled
• Within Plesk and Mailenable the entries for Blacklists are equal

Who can help me out?

Thanks for your help
Michael
