phpBB SMTP Auth settings

I’m trying to get mail from my phpBB forums working. I’m not sure which SMTP authentication method to use with the JodoHost mail servers.

I have to choose between:
PLAIN
LOGIN
CRAM-MD5
DIGEST-MD5
POP-BEFORE-SMTP

None of them really seem to be working, actually. I’m testing trying to send to my home email account. Maybe my ISP is blocking.

Thoughts?

Okay, maybe it doesn’t matter which I select. I just got a batch of a half-dozen activation reminders that I had sent out during testing this morning. I had been trying various combinations of settings. Must be that mail from here to my ISP was just delayed.
