Message sizeΒΆ

The message-size rule matches when the posted message is bigger than a specified maximum. Generally this is used to prevent huge attachments from getting posted to the list. This value is calculated in terms of KB (1024 bytes).

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

For example, setting the maximum message size to 1 means that any message bigger than that will match the rule.

>>> mlist.max_message_size = 1 # 1024 bytes
>>> one_line = 'x' * 79
>>> big_body = '\n'.join([one_line] * 15)
>>> msg = message_from_string("""\
... From: aperson@example.com
... To: _xtest@example.com
...
... """ + big_body)
>>> rule.check(mlist, msg, {})
True

Setting the maximum message size to zero means no size check is performed.

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

Of course, if the maximum size is larger than the message’s size, then it’s still okay.

>>> mlist.max_message_size = msg.original_size/1024.0 + 1
>>> rule.check(mlist, msg, {})
False
