As per the previous ticket, emails are sent from AdminTools, but blocked locally by SpamAssassin before leaving the webserver. I then get an email generated by the webserver, which is then sent to the same destination address ironically, saying that the email was blocked. The original emails never even exit my host.
I've configured SpamAssassin from my cpanel to whitelist the appropriate "from" email address. This has not helped. Emails are still blocked.
I increased the score at which SpamAssassin detects a message as spam (from 8 to 20). This helped for a bit, but then they broke this score too. The score keeps going up. It is making SpamAssassin less effective on incoming emails.
Not all AdminTools messages are marked as spam, even though the content is pretty much the same. Most are fine.
I believe SpamAssassin is gradually increasing the score associated with some AdminTools emails and so more and more will start to be blocked.
I would like to know how to whitelist them or reduce the score as you suggested in the previous thread.
I also directed one of the emails to "isnotspam.com" to see what scores are being allocated. The SpamAssassin part is below. This score was relatively low, however, as I can't actually send a blocked email to isnotspam... because they are blocked.
The scores of one blocked email before today was 20.3. Today three were blocked at over 30 even though three emails generated at the same time for similar IP addresses were not marked as spam at all.
I'm therefore not convinced that the addition of ~1.5 from the X-Priority is the complete answer, although it may be part of the solution, because the total scores are now upwards of 25-30.
Just a hint at the code I'd need to change to reduce the score would he helpful. I know you don't support SpamAssassin, but you do seem to know what the solution might be, and it is AdminTools emails triggering it.
