And so I did... It works!

Certainly not. I barely know what they are good for. You see I have a
lot to learn...

Yes, but I want to upgrade to potato as soon as the CDs are easily
available for me. I downloaded quite a big part of slink from the
Internet (about 210 packages) and I have a *really* slow connection,
so I don't want to go through this again.
I will need potato for X. The slink version doesn't work for my video
card.

I'm not surprised to read that.

nmap now gives me the following list:
Open ports on woof (127.0.0.1):
Port Number Protocol Service
25 tcp smtp
111 tcp sunrpc
515 tcp printer
...though I still don't know what sunrpc is good for.

eximconfig says:
Mail for the 'postmaster and 'root' accounts is usually
redirected to one or more user accounts of the actual system
administrator [...who is me...]. By default [...] mail for
postmaster and for various system accounts is redirected to
root, and mail for 'root' is redirected to a real user [...]
Which user account(s) should system administrators mail go to?
Enter one or more usernames [...] Enter 'none if you want to
leave this mail in root's mailbox - NB this is strongly
disencouraged [...]
By entering 'andy' I have got messages from my system delivered to
/var/spool/mail/andy.
I have to explain that this isn't really local delivery as I have a
standalone PC with no LAN. It just goes from localhost to localhost.
This happened several times and I felt nothing bad about it.
Isn't this common practice? If not, what else should I enter?

Shouldn't inetd.conf have been updated during the installation of exim?
Perhaps it is a bug in the exim package, but I haven't checked the bug
report yet.

And so I did. Mail is now delivered to /var/spool/mail/andy just like
I thought. Thank you very much again.
The next thing will be setting up mutt.

I will have a thorough look at your .muttrc...
