What can I disable, but still send mail via PHP?

Exim, SMTP, etc?

I use Google for my email, so I want to disable all email related services on my server. However, I still want to send out emails with the server (user signups, forgot password).

My understanding is that sendmail doesn't need exim, imap, pop3, smtp services to send mail OUT, that's just for mail coming IN. Am I correct?

Also, what port does it use to send mail out? I'd like to firewall off all the other ports while I'm at it.

Thanks in advance!

You need a Mail Transfer Agent to send the emails. SMTP is the transmission protocol used. So you need something like Postfix, Exim, or Sendmail if you swing that way (I'd avoid it). IMAP/POP3 are protocols used for mail retreival, so won't need any of those.

SMTP works over port 25.

Just make sure you have access to to the root/postmaster mails on the server, as mail errors are usually sent to those accounts.
