Kolab Host, Relaying Email from foreign mail server.

[Eric Renfro]

Hmm... Still no help? 

So I've been digging a bit deeper, and decided to poke at things. I went and disabled the line in the master.cf:

-o smtpd_data_restrictions=$submission_data_restrictions

Which is the data restriction policy from Kolab. I'd like to not have to do that, but actually get it to where it could work properly.
