We have an existing SMTP server running GroupWise where we wish to
consolidate email delivery for users and applications.

What is the best way to send mail from within a .NET application via this
external (to the Web server) SMTP server?

SMTP + relay + auth in an IPSEC tunnel to connect to our primary SMTP mail
server (GroupWise) from the Web server looks like it would work fine, but is
it the best way?

I am aware of CDOSYS and some commercial DLLs that allow devs to send mail
from within .ASP and .NET without local SMTP service running but I am not
sure how secure this is.

Is there any OTHER way to connect to an external SMTP server securely for
mail delivery from a .NET application?

Hello Shannon,

..NET has no built in support for SMTP over TLS.

So sending to the local SMTP relay and using IPSEC for mail forwarding sounds
good to me.
