Spam and virus filter stopped working

    I have a server set up mostly following the perfect setup for Debian 4. It's been working fine for about 2 months now. Today I suddenly got a heap of spam in my inbox. There were no more headers in the messages indicating that they had been scanned by my server. These headers used to be there but simply vanished. I can't find anything in any logfile that makes sense to me (mail.log, mail.err, mail.info, syslog, messages). It also appears as though freshclam stopped updating after yesterday.. for no apparent reason. I upgraded to the latest version of ispconfig just now, but that doesn't help.

    I only have a fuzzy understanding of how the whole process goes from mail arriving at my server to it being delivered to the mailboxes. Can anyone tell me where to look for clues?

    Any errors in your mail log? What are the outputs of
    Code:
    df -h
    and
    Code:
    repquota -avug
    ?

    By the way. I was mistaken. Freshclam is still updating. It's just that mail filtering seems to have stopped working.

    Disk space or quota are not the problem.
    Can you run
    Code:
    /home/admispconfig/ispconfig/tools/spamassassin/usr/bin/spamassassin --lint
    ? What's the output?

    Hello Falko,
    I tried to run the command you posted. The server is busy for about half a second and then returns the prompt to me. There is no output, and I haven't been able to find any errors in the mail logs for the past days (starting when filtering was still working).

    With kind regards,
    Bas
