I setup clam and amavis on my e-mail server a few months back. Since then, I have noticed a bunch of amavis-unpack-xxxxxxxxxxx directories that have built up in the /var/spool/amavis directory. The directories have a parts directory that is empty and an email.txt file that is 0 bytes in size. Are these directories safe to delete? I was cleaning out the quarantined viruses when I noticed them and would like to get rid of them if possible.
Thanks
