Can anyone assist us?

We have migrated from a Cobalt Raq to a Celeron using Plesk 7.

Our mailforms are not working properly now. The cgi script is the popular formmail.pl

The script executes, but does not send out e-mail.

Here's how we have it configured to send mail:

$mailprog = '/usr/sbin/sendmail';

Could the problem be in this line?

no that should work,

look in your apache log file for an error,

the plesk sendmail wrapper passes on to qmail, which picks up more errors in the header.
