That's correct. '*' in a Python regular expression means "zero or more of the preceding subexpression, in this case the letter "m" (more precisely, the character class "[Mm]" since we set the match to be case-insensitive).

If you want to catch the literal string "*spam*" anywhere in the subject, you need to escape the '*' with '\' like this:

^subject:.*\*spam\*

If that's not what you want, you'll have to tell us what you do want.

Of course.

The filter matches a line

• beginning with "subject:"
• followed by zero or more characters of any kind ("." means "any character", "*" means "zero or more occurences")
• followed by the letters "spa"
• followed by zero or more times "m"

Subject: RE: [RE-wrenches] Xantrex XW4548 lifespan

1. The line starts with "subject:".
2. After that, there are zero or more characters of any kind, namely " RE: [RE-wrenches] Xantrex XW4548 life"
3. After that, there is "spa".
4. After that, there is no "m" (zero or more occurencens).

That's a match.
