I hear ya... I have encountered that also before. I wish I could help. I only mentioned the css because it worked for me... I wish I could figure your problem out.....

Actually, after reading this post I am seeing something a little different now. I was under the impression before that your site was just not sending e-mail...

If it is not sending e-mail notifications it could just be a setting in general options..... Have you checked that???

What modifications have you done in the recent past that could have possibly caused this???

I haven't checked into this problem for a while, and now it just works fine. Honestly I have no idea what caused that change. As I was newly installing and configuring my message boards I changed a lot of things, installed plug-ins, etc. so I guess it's impossible to find out what the problem was and how I solved it by accident.

Thanks anyway for your help. I really appreciate it.

Everything was working great went with new server out of no where mail stopped working right in the middle of my board opening up? contacted server today like 5 times sunday tho no answer man this is beyond frustrating

I've got a problem with emails too. Although I receive all the notifications about new posts and new members as well as the site feedback regularly, other emails such as welcome messages, subscription notifications, passoword reminders, and email verification messages are never sent, which thwarts contact with the members of our forum and gets me very frustrated. The weirdest thing is that I've discovered the problem only slightly over a week ago, though it has apparently existed since about mid May. I've posted a question about this on vB.com as well:
