Hi chnaresh,
This is the code I use to send mail, it's not specific to gmail, but it works. The "props" object expects the usual mail properties, "mail.smtp.host", "mail.user" or "mail.smtp.user", as well as "mail.smtp.ssl" which you'd want to set to "true" if you're using gmail. It also expects "mail.smtp.passwd" or "mail.passwd" which my gut tells me is unsafe, but I'm not sure why.
Good luck,
