Thanks GS, MikeB, MikeD, Clive Lamb for your time and input. I really
appreciate. I installed "Outlook Redemption" suggested by Clive Lamb and the
it works OK (for now). The security warning stopped. Although I would love
to have intrinsic VB solution to this proble,

Again thank you all for helping... much appreciated.

I'm not really familiar with IMAP, but isn't that
only for retrieval? I don't understand why you
can't use VB SMTP code (like vbSendMail) to
email through gmail. There are specs here:

Is it possible that you used the wrong port?
(Most email now requires authentication, using
port 587 rather than 25, but using authentication
is not problematic in terms of coding it.)

I noticed that gmail
SMTP also uses a secure logon. That might be
an issue. I don't know what's involved in doing
that, but it might be worth looking into. It would
probably require checking whether a secure
connection is required during the initial EHLO
exchange (which is easy) and then being ready
to encrypt the communication (which may not
be easy...I don't know). There's a page here
about TLS:

If you figure it out maybe you can post the
code back here. :) It looks like it probably
requires at least an additional encryption
lib., though. (capicom?)
