That's what I thought, but then why does '^(OK|WARN|CRIT|UP|DOWN) ->' not lead
to an email with the respective topic but '^(OK|WARN|CRIT|UP|DOWN)' does?
It think this is an issue that was fixed in Mailman 2.1.19 by
https://bazaar.launchpad.net/~mailman-coders/mailman/2.1/revision/1516/Mailman/Handlers/Tagger.py
Prior to that the regexps for topic matches were compiled in verbose
mode. You indicated in your OP that the regexp for your topic was
```
^(OK|WARN|CRIT|UP|DOWN) ->
^(OK|WARN|CRIT|UP|DOWN) \-
```
Prior to Mailman 2.1.19, this was compiled in verbose mode. That worked
if the lines were simply keywords, but if they were more complex
regexps, this didn't work. The fix in 2.1.19 was to simply `or` the
lines which works more as expected.
In Mailman <2.1.19, that two line regexp compiled in verbose mode won't
match, e.g., `OK -> anything. In fact it's simpler than that. Even the
single line regexp `^(OK|WARN|CRIT|UP|DOWN) ->` compiled in verbose mode
won't match because of the space, but `^(OK|WARN|CRIT|UP|DOWN)\ ->` will.
Thus, this is a bug in Mailman <2.1.19, but you can work around it by
`\` escaping the space or using `\s`.
