freebsd xmailserver and php mail() function

[thomas may]

Hi,
 
iam using FreeBSD 4.7 and i want to change my smtp server from sendmail
to xmailserver.
i have read that the php mail() function supports only an sendmail or
qmail smtp server.
 
so what must i do, to change to xmailserver ???? i read about
sendmail-wrapper to get an solution, but
they dont work ... mainly my problem is that i have enabled smtp auth,
if i turn it off it will work.
 
thanx a lot
