Hi,
I am using RC 1.3.5 on FreeBSD, with Postfix 3.3.0
Users are not allowed to send mail with SMTP auth, there is only webmail service.
On this server I manage a few domain (<10); I would like to avoid sending message with a forget domain address (eg. I don't want that compromised mailbox can send mail with "xxxx@gmail.com", "xxxx@yandex.ru" and so on)
How can I do this?
Thank you!
