Hello,
I've noticed that there are some old messages in /var/spool/amavisd/tmp which aren't deleted

there are directories which name is like:

amavis-20140717T170345-00617-Qvxmin_F

amavis-20140721T140053-13894-abeaJIqs

I have following dirs set in amavis:

$MYHOME = '/var/spool/amavisd';   # a convenient default for other settings, -H
$TEMPBASE = "$MYHOME/tmp";   # working directory, needs to exist, -T
$ENV{TMPDIR} = $TEMPBASE;    # environment variable TMPDIR, used by SA, etc.
$QUARANTINEDIR = "/var/spool/amavisd/quarantine";

Why any messages are stored there?
I use quite little amount of storage for /tmp and it gets full quickly.

Re: not deleted mails from /var/spool/amavisd/tmp

Amavisd will extract emails to /var/spool/amavisd/tmp first, then invoke SpamAssassin/ClamAV to scan them. And i believe Amavisd will cleanup this directory.

So why there are some messages stored so long.
Please find my date, ls from dir and queue length

Re: not deleted mails from /var/spool/amavisd/tmp

Each Amavisd-new child process ($max_servers smile starts one of these in the tmp directory, once the child has done its max requests ($max_requests smile it should clean up and die and then respawn a new process.

if Amavisd-new process doesn't cleanup them correctly, i'm afraid you have to cleanup them manually with cron job. For example:

1 3     * * *     root     find /var/spool/amavisd/tmp/ -mtime +30 -exec rm -r {} \;

I suggest you wait for some more days to see whether or not Amavisd will cleanup these files.

Thanks,
I've increased /var/spool/amavisd/tmp/ from 512M to 2048M. We'll see if it's sufficient.

To speed up amavis I'm using /dev/shm

/dev/shm              2,0G  1,2M  2,0G   1% /var/spool/amavisd/tmp

Access is much faster than to disk and overall load average is lower.

I think you can cosider such config in your default installation configuration :-)

Some users have only 1GB memory on server, it's not a good idea to do this.
Considering it as a performance tuning tip.
