Try removing one or the other of these. 'mailhost' will try to use the 
perl Net::SMTP module to send messages rather than using sendmail, and 
may be getting confused.

If your sendmail is properly configured then just use this. Can you send 
mail from this server directly or have you got the smtp server set up 
correctly as a smarthost? You should be able to do a few simple tests to 
figure this out.

can you telnet to port 25 on localhost and/or the smtp server?

What happens if you try something like:

$ echo "hello" |mail me at mydomain.com

on the command line?

Are you getting any messages in /var/log/maillog that might indicate 
what is going on?

If sendmail is not working then try the mailhost line instead and see 
what happens. I use this on some of my systems where for security 
reasons there is no local MTA and it works fine.

Hope that helps,
