I've been using WP for about 3 years now. Started on wp.com and went to self hosted with GoDaddy just over a year ago. Until around Christmas Eve, the site was sending comment notifications and form submissions (I'm using cforms) without fail. Then it stopped cold.
I've checked all my admin and cp settings to verify my email address is still there and both "Email me whenever" boxes are checked under discussion.
GoDaddy says their side looks fine and MX records are set correctly for my Google Apps account. The support tech said I might need to do a clean install of WP... that sounds daunting!
I've read some threads about using plugins to facilitate an SMTP solution, but am not convinced that will solve my issues fully... I still need to use Google apps to handle my email (not GoDaddy's) and with GoDaddy it looks like I only have a daily smtp relay limit of 250. If the site was working perfectly before, what would stop it now?
Has anyone else encountered this and fixed it? Is it possible that a php file has been corrupted somewhere?
Any help would be much appreciated (my two C++ classes from college are not helping me much and I'm looking at code that is way over my head!)
