I just moved to a RackShack Linux server with Plesk. I came off of a shared server that was using CPANEL. Anyway, vBulletin is now unable to send mail to the users. I researched this problem over at the vBulletin forum and apparently quite a few other people have the same problem. Unfortunately, no one ever posted a solution. Does anyone here have the answer?

Many thanks in advance.

Check your /etc/php.ini file.


Look for a line similar to: sendmail_path

Make sure this path points to the qmail-inject file.
