I run into situation where a server had run out of diskspace (df

I don't know for sure what happens in this situation. I would expect that
messages would be deferred with a 4xx error (temporary failure) of some sort
if they can't be written to the queue. If the messages have already been
accepted but cannot be delivered, they should still be in the local queue.
"qmHandle -l" will show what's in the queues.
What actually happened was that some emails sent via submission did
not find their way anywhere and one user reported emails missing
(emails sent from outside, that I could see marked as received in the
smtp log but that never appeared in inbox) plus saw multiple blank
emails in her inbox.
I added diskspace and when I checked the queue then it was empty.
What's the best way to act in situations like this?
Do something to free up some disk space. ;) There might be some things
(backups, logs, source rpms) in /usr/src/qtp-upgrade/ that you can get rid
of in the short term.
"Luckily" I had some temp files that I could easily remove. Munin
should have warned me about this situation but for some reason it
failed to do so. I should investigate why.
What other tools are people using for monitoring their servers, any
recommendations?
Best,
Peter

I'm curious to know if the message(s) corresponding to the blank emails
were eventually delivered once there was space available. I would expect so.
I put /home/vpopmail/domains on an NFS share, so the space utilization
on the rest of the host remains fairly constant. 8G is comfortably
ample, although you can get by with half that (w/out gui). For
monitoring, I just check logwatch output periodically.
