this was the situation on /tmp before tmpwatch installation:
[root@myhostname ~]# du -lh /tmp
4.0K /tmp/.Test-unix
4.0K /tmp/.ICE-unix
4.0K /tmp/systemd-private-U6z6hx/tmp
8.0K /tmp/systemd-private-U6z6hx
20K /tmp/mywww/blog/wp-content/uploads/wpcf7_captcha
24K /tmp/mywww/blog/wp-content/uploads
28K /tmp/mywww/blog/wp-content
32K /tmp/mywww/blog
36K /tmp/mywww
4.0K /tmp/systemd-private-AFkUHw/tmp
8.0K /tmp/systemd-private-AFkUHw
4.0K /tmp/.webmin
4.0K /tmp/systemd-private-cTDFgP/tmp
8.0K /tmp/systemd-private-cTDFgP
4.0K /tmp/.font-unix
4.0K /tmp/.XIM-unix
11M /tmp/systemd-private-jr1YKi/tmp
11M /tmp/systemd-private-jr1YKi
4.0K /tmp/.X11-unix
4.0K /tmp/systemd-private-0qkmRa/tmp
8.0K /tmp/systemd-private-0qkmRa
16M /tmp
Then, I set up tmpwatch to do its job on /tmp every 12 hours...
BUT really, is not yet clear why that error about "Disk quota exceeded"
happened... and this is a problem if I don't understand, 'cause it could
be repeated.
tmp folder issue and so why? mail quota? Do you really think that is not
because of user mail quota and temp files produced by Spamassassin and
ClamAV ? are you sure?

4) user just reached 19.05 MB of his mail quota at that time
5) then I raised the user quota to 250 MB... BUT...
...questions are:
1) spamd can require even more than 30 MB of temp files to check an
incoming email? or this together with ClamAV ?
2) how can I know what's a good margin of additional space the user
should keep in mind?
3) eg. mail quota 250 MB, 200 MB for emails and 50 MB as margin for
email checking, to be sure?
4) how can I calculate this margin more or less exactly?
5) OR is possible to automatically prevent such a situation?
BEST REGARDS
HAPPY HOLIDAYS!!!
The reason that failed would seem to be that the partition that /tmp is
mapped onto became full. This is nothing to do with a user's mail quota
unless you're putting /var/spool/mail in the same partition as /tmp
So, questions for you:
1) is /tmp in its own partition and, if so, how big is that partition?
Is it big enough to contain
no_of_users * user_mail_quota
as well as the temp space normally used by the rest of the system?
2) How often is /tmp cleared?
3) If /tmp maps into a shared partition, what other top-level filing
systems does it share the partition with and how much free space
is there in that partition?
