The email.txt and parts directory are intentionally left intact so
the filesystem doesn't waste the time to recreate them for each
The parts directory will normally be empty when amavisd is idle, but
will have leftover files if there is a problem. These files are not
cleaned automatically, as they may need to be examined for problem
These files and directories are security sensitive *must not* be
world-readable since mail in transit is processed here.

Don't do that. The amavisd tmp directory must be readable *only* by
amavisd and any optional virus scanner. Please refer to the
installation notes for further instructions.
