Sending email via port 465 (1 reply)

I have a program that sends mails via port 465

// Start a SMTP session
MySession is EmailSMTPSession

MySession..ServerAddress = "mail.myserveraddress"
MySession..Port = "465"
MySession..Password = "MyPassword"
MySession..Name = cSender
MySession..Option = optionSSL

It work at all the clients except one.
It is a client who has also security camera's. All the ports on the router are closed.
So I told him to open port 25 and 465.
But it still does not work.

Someone an idea. Are there other ports that have to be opened.

Thanks.
Willy Hermans.
