This does not work in SmarterMail Enterprise Version - 100.0.6956

I've added the .doc extension and tested in both incoming and outgoing and we will receive these attachments.

Restarted the SmarterMail service after setting this up.

Steve,

I believe you may need to add the extension without the "." in front of it (i.e., just "doc" instead of ".doc").  Could you give that a try and let us know the results?

Hey Ben, 

Still processing emails (delivering .doc attachments) with attachments once updating to doc without the ' . '

My doc file is a simple text file renamed to test.doc which properly shows as a Word Doc when reviewed in detail.

Steve,

Have you tested with an actual .doc file created directly in Word by chance?

Just tested and that also passed through without interruption.

Steve,

Thanks for testing that.  The next thing I could suggest to try would be a minor update to the latest version of SmarterMail as build 6956 is about 17 minor versions behind:

Ben,
I'm trying to hold off on the updates as they have been cost-prohibitive as well as sometimes introducing other issues.

Do you know where in one of the config or xml files this extension block is set? I can then review the raw configs to see if there is an issue in the setting of this parameter.
