Currently running Plesk and we modified the mailer.conf in order to make sure it was using qmail. However, when users use:

/usr/sbin/sendmail (which symlinks to /usr/sbin/mailwrapper) users cannot send mail.

Many customers point scripts to /usr/sbin/sendmil and if they use /usr/lib/sendmail it works just fine. The mailer.conf setup we have is:

sendmail /usr/local/psa/qmail/bin/sendmail
send-mail /usr/local/psa/qmail/bin/sendmail
mailq /usr/local/psa/qmail/bin/qmail-qread
hoststat /usr/local/psa/qmail/bin/qmail-qstat
purgestat /usr/local/psa/qmail/bin/purgestat


I tried changing it to point directly to /usr/lib/sendmail but this does not work.
