What version of JavaMail are you using?

If you turn on Session debugging, what does the debugging output show?

Also, try setting the System property "mail.socket.debug" to "true" for additional debugging output related to certificates.

I don't know anything about Velocity so I have no idea how those property settings in your code are getting to JavaMail, but it seems quite possible that they aren't, which would explain the problem. The debugging output will help verify what's really going on.
