I just spent the better part of an hour running down a bug with my new web host. The PHP function mail() is great if it works. It sucks when it doesn’t because I can find very little information on how to troubleshoot it. By luck, I happened to Google my host’s name along with “mail() not working” and found an answer.
Sometimes it pays to search closer to home rather than all over the web, I learned. At least now I know why it didn’t work. Next time I’ll be more careful, I suppose.
