[rt-users] RT Email temp fail with ExternalAuth and Auth::MailFrom

[Shawn Plummer]

I am pretty certain I have something configured incorrectly regarding commandbyemail 0.9 ExternalAuth 0.9 and RT 4.0.1 (though its a problem for me with our 3.8 installation)

Our externalauth plugin is configured to not create users that do not exist in our AD server. We don't want a user to end up with multiple rt accounts if they send from their campus email then from their home account then from a different account etc. Sending with a valid AD account works fine and commandbyemail processes emails just fine.

However this causes a problem with email when sending an email as a non valid AD user. I get this error.

Aug  2 16:18:08 rtdevel postfix/local[3050]: B534D5A57E: to=<rt at rtdevel.geneseo.edu>, relay=local, delay=2.2, delays=1.6/0.02/0/0.62, dsn=4.3.0, status=deferred (temporary failure. Command output: RT server error.  The RT server which handled your email did not behave as expected. It said:  Can't call method "HasRight" on an undefined value at /opt/rt4devel/sbin/../lib/RT/User.pm line 1206.  Stack:   [/opt/rt4devel/sbin/../lib/RT/User.pm:1206]   [/opt/rt4devel/sbin/../lib/RT/Queue.pm:1262]   [/opt/rt4devel/sbin/../lib/RT/Queue.pm:1229]   [/opt/rt4devel/sbin/../lib/RT/Queue.pm:657]   [/opt/rt4devel/local/plugins/RT-Extension-CommandByMail/lib/RT/Interface/Email/Filter/TakeAction.pm:496]   [/opt/rt4devel/sbin/../lib/RT/Interface/Email.pm:1612]   [/opt/rt4devel/sbin/../lib/RT/Interface/Email.pm:1429]   [/opt/rt4devel/share/html/REST/1.0/NoAuth/mail-gateway:61]  )

The problem is because its status is deferred the user gets spammed with failure messages every time the queue runs till the deferred message is out of the queue. It only seems to set it to deferred when I have the mail plugins Auth::MailFrom Filter::TakeAction enabled. if I disable them it just fails, sends one bounce message and moves on as I want it to do.

Am I missing some critical config line for Auth::MailFrom or Filter::TakeAction that would make it not defer?
