Hi everybody,
i'd like to close smtp relay but horde webmail.
So I setup outgoing mail limit to 0 in mail server setting and I white list localhost (127.0.0.0 / 8, ::1 / 128).
Anyway, email messages sent from horde webmail are blocked by outgoing mail limit.
Why?
Ok, the problem is not authentication. I don't want open authenticate realy because some users get spam malaware. So I only need to send mail with horde webmail. White list works well. Thank you
