[Assp-user] forwarded spam affecting the server reputation

[PlusPlusHosting.Net <plu...@gm...>]

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.
