mail from joomla not working

[pera]

Have been testing some strange thing with mail. This is new server with 3 user.

when I send mail from outlook to [email protected] there is no problem.

when I send email from joomla or other script on server.com to outside the server there is no problem.

But if I send email from joomla or other script on the server.com to email on the server.com I get error:

A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator.

this is multiserver setup.

where to look

I found the solution...

I have sendmail installed!

cd /usr/sbin
cp sendmail sendmail.old
cp exim exim.old
rm sendmail
ln -s sendmail exim

Furthermore, you should confirm Exim is working like it should, as DA should remove Sendmail when first installing it.

I can at least recive and send mail! But have not unistall sendmail (will I get in problem if I do? % risk).
Added:
sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"

in rc.conf

Haven't used Sendmail, with DA here.
If you're sure Sendmail is disabled, and won't ever come back, just let it be there.
(Never try to fix something that's working, you might end up breaking everything )
