[Enigmail] Enigmail and IMAP external caller

[Larry LeBeau]

Enigmail List,

I am the software developer for a utility written in Visual-Basic which 
uses MAPI Session/Message Controls (came with the compiler,  Version 
6.0) to generate emails.  When Thunderbird is open, it interfaces very 
well and email messages are sent accordingly.  However, a number of the 
users have now had Enigmail installed and the emails are failing. 

I have tested my own Enigmail installation and likewise outgoing emails 
fail with Enigmail installed, and work when it is not installed.  During 
my various attempts, I stumbled upon a configuration wizard (via the 
"Select Key..." button under Account Settings), but I can not seem to 
get back to it.  This wizard had a check box that referred to "IMAP 
parts" and something about allowing external execution.  I am inclined 
that this may be a key setting, but I can not seem to find any related 
info on the preference screens, or the web, so I am seeing if anyone can 
help me with finding that setting, or any other related advice or 
assistance.

Thanks in advance,
Larry LeBeau
