I had to reset something with SELinux that was preventing the forums from invoking the sendmail process, which randomly popped up on a software upgrade. I officially hate SELinux even more than when I had to set up the exemptions just to get the forum script working in the first place.
If this happens again, I am outright disabling SELinux. Piece of crap.
Kudos for continuing this thankless job!
Still the best forum. Ever. Thanks for all.
