Well, somehow I missed the “READ THIS FIRST – BuddyPress 2.5 Master List” sticky topic! CRAP! I guess I was too busy searching the forums to browse the first page. 🙁

On some sites, emails aren’t sent, or not delivered.
This issue is under investigation. Some fixes have been made for v2.5.1. — 6947

So, maybe it’s not such a mystery that BP emails are not being delivered and my long winded “story” really wasn’t necessary.

The quick summary of the above is:

For any recipient on a remote mail server (google, yahoo, hotmail):

1. Friend request email is being sent and delivered (html)
2. PM email is being sent, but not delivered (html)
3. Mention email is being sent, but not delivered (html)
4. Other email sent by BP Plugins and by WP is being sent and delivered (plain text)

For local recipients (Email addresses with site domain – co-located Mail server):

1. All mail is delivered

Is there anything different about the 4 email scenarios above?
Any reason why #1 (html) and #4 (plain text) would work while #2 (html) and #3 (html) don’t?
Any reason why my co-located mail server would accept all the mail without issue?

This would be easier to understand if all html email was not being delivered, but this isn’t the case. The Friend Request html email is consistently working fine.

Any troubleshooting ideas are most welcome.
