Ask Bjørn Hansen a23d4b3da9 Fix 01-syntax test failures
Exclude some tests with dependencies.

Remove -T from perl line in plugins
This makes it harder to test with PERL5LIB/perlbrew etc

=head1 NAME
auth_vpopmail - Authenticate against libvpopmail.a
=head1 DESCRIPTION
This plugin authenticates vpopmail users using p5-vpopmail.
Using CRAM-MD5 requires that vpopmail be built with the
'--enable-clear-passwd=y' option.
=head1 CONFIGURATION
This module will only work if qpsmtpd is running as the 'vpopmail' user.
CRAM-MD5 authentication will only work with p5-vpopmail 0.09 or higher.
http://github.com/sscanlon/vpopmail
Decide which authentication methods you are willing to support and uncomment
the lines in the register() sub. See the POD for Qspmtpd::Auth for more
details on the ramifications of supporting various authentication methods.
=head1 SEE ALSO
For an overview of the vpopmail authentication plugins and their merits,
please read the VPOPMAIL section in docs/authentication.pod
