Hello!
Is there any way to hook into SMTP transport in Outlook 2007 and pick
up messages that goes to SMTP server?
One of the spam filters awhile back had a novel approach, it installed a
pseudo SMTP server that listened to the loopback address, and played
man-in-the-middle between Outlook and the real SMTP server. Outlook was
configured to use localhost as its SMTP server, and the pseudo-server was
configured with the real server details.
The benefit was that it was virtually guaranteed to work with ant SMTP
client software, without need of addins, extensions nor other carnal
knowledge. One drawback (from the outside looking in) was that
communicating server errors back to the client was a little funky -- how
does an SMTP server tell an SMTP client that the server isn't answering?
Otoh, it's not like Outlook is exceptionally forthcoming in such cases, so
little was lost (imho.)
As for how much work it would be, figure you're implementing both sides of
the exchange; I'm sure there are any number of open source projects for both
sides, find one you like for each, integrate them and splice-in your
functionality. (Makes it sound trivial, doesn't it?)
