vBulletin emails not working...
 

Hi folks,

Please bear with me, as I'm ultra new here, and also new to administering a vBulletin board. I recently implemented version 3.7.2 of vBulletin and everything was working swimmingly, including emails going out when folks where registering, subscription emails, PM notification emails, etc. On the weekend, I upgraded to version 3.7.3, and again the upgrade went smoothly and everything seems to be working fine except for emails.

Somehow I've inadvertently broken emails from working at all in my forums and I'm not sure where I've gone wrong. If I go into the AdminCP -> Diagnostics and try to send myself an email, the following appears:

SMTP: localhost
sendmail_from: None
sendmail_path: /usr/sbin/sendmail -t -i

But I do not receive any email at all.... ideas? If I need to provide anymore info, please let me know.

If no error is returned in the diagnostics, then the problem is most likely not in vB. Try checking your mailserver logs, or ask your host to look into this.

Hmm.... except the problem only began immediately after upgrading from 3.7.2 to 3.7.3, which does point to something I've done wrong with the upgrade.
