Send from domain IP addresses MailCleaner CBL

 

I have a customer that got listed on CBL using Mailcleaner.

I found this.

If you have mailservers relaying through your mailcleaner cluster, do not turn on “Mask IP address of relayed host on port 587” OR “Masquerade relayed HELO with sender domain” as you wil find yourself listed very quickly in the CBL.abuseat.org RBL, which is part of Spamhaus XBL, and hence can unleash a world of pain if you get listed.
