fetchmail, mutt, mail

[Schoppitsch Dieter <dieter.schoppitsch@uta.at>]

Hi,
what is going wrong?

Dialing in to my ISP (with pppd) and fetching mails (with fetchmail) works well.
But then I get the message "SMPT connect to localhost failed" respectively (using fetchmail -S hostname)
"This message is MIME format. Since your mail reader does not understand".

* Where can I see/set my local smtphostname (or should I set my domainname)?
* Sending myself a mail (with mutt) doesn't work - which address should I use (root or root@hostname doesn't work)?

Thanks for any help
Dieter
