Hi, As it was mentioned you have to configure -f flag in sendmail arguments in RT site config. Also, some MTAs (sendmail (tm) and may be other) may mention that return-path was adjusted, to avoid such mentioning you should mark web server's user (apache, www, httpd or how it's named on your system) as trusted one by adding it to /etc/mail/trusted-users (may depend on MTA, double check file name as I just wrote it from memory).
