My /etc/inetd.conf looks like this:
#:MAIL: Mail, news and uucp services.
smtp stream tcp nowait mail /usr/sbin/exim exim -bs
nntp stream tcp nowait news /usr/sbin/tcpd /usr/sbin/leafnode
#:INFO: Info services
finger stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/in.fingerd
ident stream tcp wait identd /usr/sbin/identd identd
These are the only lines that are not commented out. Try to copy the
line for smtp from above, it should work.
Do you actually need all the things you have running?
Is it slink you use?

It isn't a very secure setup on anything but a ``trusted network'',
whatever that is.
As you are on a dial-up like me, you probably don't need any of these
ports, nmap of my machine:
Port State Protocol Service
22 open tcp ssh secure shell.
25 open tcp smtp EXIM!!!
79 open tcp finger nifty thing, not important.
80 open tcp http Apache, dwww on-line docs
113 open tcp auth identd, for IRC ...
119 open tcp nntp leafnode newsserver.
515 open tcp printer ...
1024 open tcp unknown What is this??
6000 open tcp X11 ...
Ports 79 and 113 could be shut down ... but doing that isn't very
inportant for me.

Sure!

It should be something like mine: hotpost.dk, with just ``woof'' you
mail will look like <username>@woof, and that's not a valid e-mail
addresss.

This is good, fetchmail rewrites the headers to say
<username>@localhost, but exim allways accepts localhost by default ...

Good.

Probably OK.

OK, I tried to say Yes, with no ill effect, and I'm on a dial-up type
cable connection.

I use ``none'' here, but this is probably OK.

Is ``andy'' your username? If so, your outgoing mail will claim to come
from andy@woof with this setup, hardly what you want.

So it is just a broken inetd.conf.
Fix it as per above, and do a ``killall -HUP inetd''.

Happy to be of help.
