I upgraded MySQL, PHP, and Threads this weekend. Since then, new users get an error when registering:
Warning: mail(): Could not execute mail delivery program '/usr/sbin/sendmail -t -i ' in /Volumes/Data/WebSites/www.realtree.com/forums/ubbt.inc.php on line 211
Line 211 looks like this:
mail("$to","$subject","$body","From: $from{$newline}{$bcc}$headers","-f{$config['emailaddy']}");
