Thanks Ken, I didn't have tools for signing codes in VB.
On MS site I found CAPICOM tool and with it now I am able to sign my add-in.

To add to what Dmitry said, the way some things like Norton operate is to
replace your account settings with a link to localhost where they install
their own SMTP server and trap the outgoing/incoming mail that way. Once
they finish screwing up the message they then forward to the real servers
from the account properties you originally set up.

I have no problems signing my COM addins created using VB 6. The language
is never an issue. If you create a DLL for a COM addin, or an OCX for a
property page you just use your signing certificate on that. I use a
Thawte code signing certificate and can do that as well as sign my MSI or
setup.exe installation packages.

Hello Ken,

Thanks for the response. The link you gave is excellent.

First thing I want to ask, is there a way to digitally sign add-in
created in VB6?
I created a test add-in for outlook and with security level set to High,
it won't
load add-ins which are not digitally singed and trusted. Until now I only
used macros
which can be so easily signed with a digital certificate.

Second thing: there are many antivirus programs like symantec etc., which
"I THINK"
do catch event when outlook connects to an smtp or pop3 server and proxy
for the
end servers.
(The reason I believe they catch this event, is that if the smtp or pop3
server is un-reachable,
those antivirus programs just don't come in to picture and keep silence.)

I did lot of web search in past few hours about catching this event but
in vein.
I am very qurious how those antivirs folks manage it.

Regards

Sharad
