This is the information provided by Gmail: http://mail.google.com/support/bin/answer.py?answer=13287 http://mail.google.com/support/bin/answer.py?answer=13287
Outgoing Mail (SMTP) Server - requires TLS or SSL:
smtp.gmail.com (use authentication)
Use Authentication: Yes
Port for TLS/STARTTLS: 587
Port for SSL: 465

However, I tried both port numbers but neither of them work.
What is the correct setting for ClamWin to send email through Gmail server alerts upon virus are detected?

Thanks.

Not a direct answer to your question, but I've found ClamSentinel a very, very good scanner for webmail, email, etc., regardless the browser, email client and configuration or webmail app.

clamwin does not support TLS or SSL and is not compatible with gmail

Is it not possible to add SSL support to the ClamWin emailer
