Mail from sendmail - exim

[rozinante]

Hi,

I'm testing for send mail to my account from logwatch or jobs in my crontab, but I don't receive any mail.

It's necessary config someone parameter in exim for this?

If I test with "mailq" , my server show : postqueue: warning: Mail system is down -- accessing queue directly

It's normal?

Thank you

Do you really use exim or it's postfix??
