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
