Here’s my guess at what’s happening.

 

Home machine with Outlook as a client on Roadrunner cable.

 

Mail server is on an edu IP block.

 

Roadrunner (themselves) put their IP block on one of the RBL lists (http://www.spamhaus.org/pbl/query/PBL238567)

 

As a result if I try to send an email from Outlook at home (outlook 2013 on win 8) using MY mail server as SMTP (not roadrunners), my server see it as coming from a blocked address and refuses to accept it. I put my home IP in g_orbs_exception and all is fine.

 

Should RBL also be included in g_smite_skip_auth ? or am I mixing things up?. Been using Surgemail since dMail and this came up rather recently.

 

Thanks,

Jeff
