Wonder if anyone can help me with this...

I recently upgraded to 4.4.0 and moved server, and as part of that set up bounce processing for the first time.

Initially I set up outgoing mail to use mail(), but noticed that I was getting a lot of bounces from AOL. I set up a test account with AOL and found that if I changed CiviCRM's outbound mail settings to use SMTP, then I could receive CiviMail at my test AOL account. I think this is because the web server's IP shows up in the mail headers and fails AOL's rDNS check (if I use SMTP, then the actual IP of the mail server shows up in the header - it has a good reputation with AOL, so the rDNS passes, possibly...).

The problem I have now is that when using SMTP for outbound, mailing jobs are failing to complete. I've done one mailout to 4000 or so today, but it seems to have stalled at 1200 deliveries. The job is still running after a few hours but the delivery count is staying the same, so I think there may be a problem... When using mail(), a similar job would complete in a few minutes. Is this normal with SMTP?

Lastly, I'm still seeing a lot of syntax bounces. This seems to be about the same with either mail() or SMTP.
