Can I control which
port number gets used when messages are sent via the web
interface?
Here's why I want to
know:
We use POPFile as a
spam filter on our email server. It acts as an SMTP proxy, and runs
on port 25. It hands off email to IMail's SMTP server running on port
26. All of our inhouse desktop clients use SMTP over SSL, on port
995. This traffic automatically bypasses the spam filter. Now that
the webmail uses IMAP, it appears to use the standard port 25 when sending mail,
which then goes through our spam filter. As a result, some of our outgoing
mail can occasionally get classified as spam. Typically we would whitelist
an email address, but this one is fairly generic and tends to recieve a lot of
spam so I want inbound messages to still get filtered.
Any
ideas?
