Bug#871575: lintian: maintainer-address-causes-mail-loops-or-bounces should be fixed to allow @packages.debian.org emails

[Raphaël Hertzog <hertzog@debian.org>]

Package: lintian
Version: 2.5.51
Severity: normal

I believe that the check maintainer-address-causes-mail-loops-or-bounces
should no longer refuse "*@packages.debian.org" in the Maintainer field.

I did patch the code generating the aliases on packages.debian.org to
avoid mail loops:
https://anonscm.debian.org/cgit/webwml/packages.git/commit/?h=debian-master&id=5f4f27920e996e521d32dfb5a9693a09348d18d5

The current downsides of using such emails is:
- it might generate bounces for ftp-masters for the first emails
  until the package has been accepted in unstable
- Package Tracker subscribers will get duplicate emails from
  various services

Those downsides will need to be fixed but in the mean time I would
like the requirement to be relaxed so that we can try on a test package
and see what services are generating duplicate emails.

Cheers,
