I quick-fix half-hearted solution is to add a dummy virus scanner entry
which always succeeds and claims a clean status, e.g.:
['always-clean', sub {0}],
Another quick and dirty solution is to hack both code sections
which test whether to preserve or not to preserve temporary
directories. Search for (two occurrences of):
if ($self->{preserve} && !$self->{empty}) {
and replace them with:
if (0) {
The coming version of amavisd provides a cleaner solution:
- adds a setting $allow_preserving_evidence, which (when turned off)
essentially does the same as the hack above;
- adds the ability to specify a tempfailing *_destiny (D_TEMPFAIL);
- treats a failure of all virus scanners as just another
reason to flag a message with CC_UNCHECKED, and allows the
usual configuration facilities to treat it one way or another,
e.g.:
$final_unchecked_destiny = D_TEMPFAIL; # defaults to D_PASS
$unchecked_quarantine_method = 'local:unchecked/%m.gz';
Drop me a line if you'd like to try out the current snapshot.
