Maximum number of recipientsΒΆ

This rule matches when there are more than the maximum allowed number of explicit recipients addressed by the message.

>>> mlist = create_list('_xtest@example.com')
>>> rule = config.rules['max-recipients']
>>> print(rule.name)
max-recipients

In this case, we’ll create a message with five recipients. These include all addresses in the To: and CC: headers.

>>> msg = message_from_string("""\
... From: aperson@example.com
... To: _xtest@example.com, bperson@example.com
... Cc: cperson@example.com
... Cc: dperson@example.com (Dan Person)
... To: Elly Q. Person <eperson@example.com>
...
... Hey folks!
... """)

For backward compatibility, the message must have fewer than the maximum number of explicit recipients.

>>> mlist.max_num_recipients = 5
>>> rule.check(mlist, msg, {})
True
>>> mlist.max_num_recipients = 6
>>> rule.check(mlist, msg, {})
False

Zero means any number of recipients are allowed.

>>> mlist.max_num_recipients = 0
>>> rule.check(mlist, msg, {})
False
