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

=head1 NAME

|
|
|
qmail-queue
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This is the most common plugin used to queue incoming mails. A
|
|
variation of this plugin would maybe forward the mail via smtp.
|
|
|
|
=head1 CONFIG
|
|
|
|
It takes one optional parameter, the location of qmail-queue. This
|
|
makes it easy to use a qmail-queue replacement.
|
|
|
|
queue/qmail-queue /var/qmail/bin/another-qmail-queue
|
|
|
|
If set the environment variable QMAILQUEUE overrides this setting.
