Exclude some tests with dependencies. Remove -T from perl line in plugins This makes it harder to test with PERL5LIB/perlbrew etc

|
|
|
check_badmailfromto - checks the badmailfromto config
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Much like the similar check_badmailfrom, this plugin references both the
|
|
FROM: and TO: lines, and if they both are present in the badmailfromto
|
|
config file (a tab delimited list of FROM/TO pairs), then the message is
|
|
blocked as if the recipient (TO) didn't exist. This is specifically designed
|
|
to not give the impression that the sender is blocked (good for cases of
|
|
harassment).
|
|
|
|
Based heavily on check_badmailfrom.
