This change was very much needed. I lost quite a few administrators like this recently :)
--- NEW FILE: probe.txt --- This is a probe message. You can ignore this message.
I have the feeling that these messages are always too long. Most people don't feel easy reading long "automatic" texts, especially if it arrives in a language they don't perfectly master. In this precise case, the message is long, and talks about things most people have never heard of (probes, bounces, disable/re-enable subscription).
What I've done on listes.rezo.net is the following (for example, concerning subscription ack):
>>>>>>>>>> start file
%(welcome)s Your address has been added to the list %(real_name)s@%(host_name)s
Thank you.
To unsubscribe, you can write to the following address: <%(real_name)s-off@%(host_name)s>
>>>>>>>>>> end file
What I mean is that the documentation should not be inside the message (well, that's my view of this user interaction problem). If other people feel the same, we could redesign a set of shorter templates for non-geeks.
The probe.txt message is of course very difficult to write, especially if it contains a virus attached as a copy... :)
