I'm trying to send an email to a gmail address using CDO 2000 Library in Visual Basic 6. The problem is, I can't find a decent SMTP server. When I tried to use gmail's SMTP server (smtp.gmail.com) I got an error , -I believe- the cause of the error is Gmail's smtp server secuirty system (STRL or whatever), probably, CDO doesn't know how to communicate with that type of SMTP servers. I tried Hotmail's mx2.hotmail.com it works fine if the "rcpt to" address is a hotmaill address, but it wont work with any other addresses. I tried google's smtp.google.com but it rejected my "rcpt to" address (which is a gmail address), I tried few other smtp servers and they all rejected my "rcpt to" address too.

How can I solve this problem?
