I don't know what the "Topic keywords, one per line, to match against
each message." phrase is intended to mean, but here's what's going on.
The Regexp: box for the topic contains a single regular expression
which is compiled by re.compile() with the re.IGNORECASE and
re.VERBOSE flags. This means that both case and whitespace including
newlines will be ignored.
In other words, if you put
into the Regexp: box, this becomes 'onetwothree' and will only match
that exact string or one which is identical except for case.
If you wanted that topic to be a Subject: or Keywords: containing any
one of the words 'one', 'two' or 'three', you need to use the regular
expression 'one|two|three' which you could create for example by
into the box or equivilantly
Of course you could use a more elaborate regexp as well depending on
what you want, but however you enter it, it is just one regexp and the
newlines and other whitespace are ignored unless escaped or inside
