Maildrop lock busy! Is another session active?

Solution:
First make sure that you have no eudora, netscape or other mailsessions running.
Login at peppar and do the following:
cd /var/mail
cat .$USER.pop >>$USER
rm .$USER.pop
rm $USER.lock*
If this doesn't help then repeat the above steps (after exiting eudora or whatever mail reader you are using) and do the following also.
mv $USER $USER.save
cp $USER.save $USER
rm $USER.save

Can't login on unix machines (via XDM)

Solution:
Login at peppar from a MAC or PC.
Check that your quota is not exceeded.
peppar% quota -v
If over quota then remove enough files to get below quota again.
Check for the following:
.netscape/cache/...
core files (ex. find ~ -name core -print | xargs /bin/rm)
Leftover *.o files (ex. find ~ -name "*.o" -mtime +7 -print | xargs /bin/rm)
If not over quota then contact support (support@cs.umu.se or phone 9950).

HP printer complaining: 41.3 Pappersfel (Paper error)

Solution:
Press the buttons marked "Skift" and "Fortsätt" on the printer

Can not send mail: Error 550 we dont relay

Solution:
Our mailserver is (nowadays) configured to only accept delivery of mail which is either addressed to us or sent from us. This means that if you are not within the cs.umu.se domain you can not use our mail server as smtp server. Normally you should use the ISP provided mail server as smtp server for sending mail. If you are using the university modem pool or connected through the student net use mail.umu.se as smtp server.
You can still use our mail server as pop server, with the correct password of course.

IMAP4 Server Data-DO NOT DELETE

Description:
This is not an error. It's a message used (by some) imap and pop servers to keep information between different mail sessions. Just ignore the message and do what it says. Do no delete. It probably not fatal to delete but why bother.

Starting Applix gives Connection reset by peer

Description and solution:
This is caused by a crashing applix daemon. When crashing it leaves 2 files in /tmp, .axnetipc and .axsc1
If you are the owner of these files then remove them and applix will be able to start again. If they belong to someone else then send a mail to support and we will remove them for you. (Please remember to specify which machine you are trying to start applix on.)
