Hey,
I am setting up a Maia mailguard system with ClamAV for virus scanning.
I'm getting these in my logfile:
clamav.log
Thu Apr 18 18:13:40 2013 -> WARNING: lstat() failed on:
/var/amavisd/tmp/amavis-20130403T221718-26913

Thu Apr 18 18:15:52 2013 -> WARNING: lstat() failed on:
/var/amavisd/tmp/amavis-20130403T221718-26913
I have configured ClamAV to run as amavis:
mail ~ $ ps uax |grep amavis
amavis 1292 0.0 4.7 393792 194180 ? Ssl 18:12 0:00
/usr/sbin/clamd
amavis 1405 0.4 0.0 39848 1904 ? Ss 18:12 0:01
/usr/bin/freshclam -d --quiet
amavis 1896 0.3 2.0 205400 83232 ? Ss 18:13 0:01 amavisd
(master)
amavis 1899 0.0 2.1 285688 85184 ? S 18:13 0:00 amavisd
(ch1-avail)
amavis 1900 0.0 2.0 206680 81848 ? S 18:13 0:00 amavisd
(virgin child)
And if I run the scan manual with clamdscan it shows the error:
amavis@mail:~$ clamdscan /var/amavisd/tmp/amavis-20130403T221718-26913/
/var/amavisd/tmp/amavis-20130403T221718-26913: lstat() failed:
Permission denied. ERROR
----------- SCAN SUMMARY -----------
Infected files: 0

But it I run clamscan as the amavis user (The same user as clamd is
running with) manual it works fine:
amavis@mail:~$ clamscan /var/amavisd/tmp/amavis-20130403T221718-26913/
/var/amavisd/tmp/amavis-20130403T221718-26913/email.txt: OK

Generally do the amavis user have RWX rights on all the folders except
from the /var folder
Anyone have any ideas?
