- try to configure assp more strictly to detect (block or tag) those mails
as spam when they are incoming
- tell/configure exim to analyze the X-ASSP ... MIME headers (Score for
example) to prevent forwarding spam mails
It seems nearly impossible for assp to detect such a forwarded mail as
spam in outgoing direction, if it was not detected as spam at the incoming
way.

Betreff: [Assp-user] forwarded spam affecting the server reputation
Hi there, we are having issues with spam that is being forwarded to
external emails, like gmail. Is there any way to make assp do not
forward (simply discard) any message detected as spam? I mean....for
people using forwarders from the hosted domain to gmail for example.
Lately is happening a lot and gmail is lowering the server ip reputation
for this.
Here is the note from one of our techs, probably could help...

Recently i have seen an influx of emails that are stuck in the queue
that are being rejected and stuck in the queue for one of two reasons
the first is that there is no authentication information because it is a
forwarder and the second is that when these do work which I am honestly
not sure how it does, maybe because the line "-aclc
_authenticated_local_user 4" but those ones are blocked by
Google because it is forwarded spam.
This behavior is slowly but surely hurting your email reputation
although the biggest impact is likely from the high amount of emails
that are bounced to unknown users when inbound spam is bounced.
Generally what we do to address for cpanel hosts is to set exim to drop
and not bounce based on SpamAssassin score and to not forward to
external domains when SpamAssassin marks the email as spam, I am not
sure if this will work on your hosts however as it uses assp instead.

Thanx in advance!
Im using ASSP v2 and ASSP deluxe for cpanel.
