> A client of mine (www.JewFind.com) is using the PHP mail() function to

> make the delivery more reliable?

-- Use -fsomething at somehwere.com header

-- Make sure the web server's user is in /etc/mail/trusted-users if using
sendmail/etc.

-- And most importantly: relay mail through a real mail server with proper
DNS records, etc.  Many places now check for the correct DNS records and
listening SMTP ports to ensure it's a real server sending the mail.  Web
servers won't pass these tests.
