The NNTP runnerΒΆ

The NNTP runner gateways mailing list messages to an NNTP newsgroup.

>>> mlist = create_list('test@example.com')
>>> mlist.linked_newsgroup = 'comp.lang.python'

Get a handle on the NNTP server, which we’ll use later to verify the posted messages.

>>> from mailman.testing.helpers import get_nntp_server
>>> nntpd = get_nntp_server(cleanups)

A message gets posted to the mailing list. It may contain some headers which are prohibited by NNTP servers such as INN.

>>> msg = message_from_string("""\
... From: aperson@example.com
... To: test@example.com
... NNTP-Posting-Host: news.example.com
... NNTP-Posting-Date: today

... """)

The message gets copied to the NNTP queue for preparation and posting.

>>> filebase = config.switchboards['nntp'].enqueue(
...     msg, listid='test.example.com')
>>> from mailman.testing.helpers import make_testable_runner
>>> from mailman.runners.nntp import NNTPRunner
>>> runner = make_testable_runner(NNTPRunner, 'nntp')
>>> runner.run()

The message was successfully posted the NNTP server.
