Message Notification Service not working

[Dave]

OK so finally getting back to this - have posted on the smf forum but will duplicate here the detail:

My forum isn't sending out notifications, but used to do so.

It is almost certainly related to a change in host.

After speaking with my host they told me to update the SMTP credentials to those of a working email address set up inside cPanel.  (And address I already have but obviously the server will have changed from my old host) and I neglected to update it.

The SMTP credentials they confirmed:
Mail type SMTP
SMTP server
SMTP port
SMTP username
SMTP password  

so that's what I have in Admin > Maintenance > Mail > Settings

BUT it no worky.

It occurs to me that at some point (I can't recall when exactly) I switched from PHP to SMTP in the mail settings. That may or may not have been at the same time as changing hosts, but I don't think so.  It certainly may be relevant though so I figured I'd better mention it.



Suggestions welcome.

Have you tried going back to using the SMF php option using a gmail account or similar? I say this just to test if it's the SMTP settings that wrong or something more

maybe i was always smtp as notifications would come form my forum email address not gmail or anything

You can spoof the sender in an email, this is why SPF and DKIM is needed
When you make a connection to a SMTP you give it the To: and the From: address it adds it into an email and sends it away.

If you still have an older PM email you can look at the headers it will tell you what system sent it

All sorted.
Turns out for some reason port 465 didnt work but port 587 does.
