We have recently changed from a NetWare GWIA, to a OES2/Linux based GWIA. The mail is working for the most part however; we keep ending up on att, bellsouth, sbc block lists, and our users cannot send messages to those domains. We have tried to contact ATT about this issue and are only able to sign up through the website to tell them to remove us from the blocklist, for the most part other domains are fine, but this is getting to a critical condition.

has anyone seen this behavior in the past from a Linux based GWIA over the NetWare based? Is there something specific that is needing to be set up on the GWIA now that it is on Linux?

Thank you
