[rt-users] RT stripping FROM on internal emails

[Michele Hershey, CTR]

Curiously, when an unprivileged RT users is sent a comment and they reply (internal users only...same domain as RT), the FROM is stripped and the comment in not entered into RT.  This used to work about 6 months ago.

What did we change?  That is an long list.

Here is the error message:
==============
(/var/log/messages)

Feb  2 15:01:38 rt3 RT: Permission Denied (/opt/rt3/bin/../lib/RT/Interface/Email.pm:244)
Feb  2 15:01:38 rt3 RT: Could not record email: Message not recorded: Permission Denied
(/opt/rt-3.8.8/share/html/REST/1.0/NoAuth/mail-gateway:75)
=================

Any place we could start looking would be helpful.  

Thanks,
Mich
