body LOCAL_SHORT_BODY /^.{2,120}$/
describe LOCAL_SHORT_BODY Short body

I included this in my local.cf, and gave it a low score as it's not really a great indicator of spam on its own, but in conjunction with other rules I have, it works well.

The problem is, even long emails seem to trigger this rule. Why? I'm pretty sure my regex above is correct (a body of 2-120 chars).

Aren't you saying match any character (.) two to 120 times? –  NickW Apr 15 '13 at 16:29
Yes. I want to match any email that is 2-120 chars in length. Is the above expression considered Perl regex? Do I need the =~ symbol before it? –  CaptSaltyJack Apr 15 '13 at 16:36
Though it's not like it's NOT matching text.. it's matching anything/everything. –  CaptSaltyJack Apr 15 '13 at 16:40
That's what I'm wondering, it seems at first glance to be correct ^ start . any character {2,120} between 2 and 120 $ end, what I'm wondering is if it could be saying, well, up to 120 characters can be matched in a 2000 character document... –  NickW Apr 15 '13 at 16:42
So, if you add =~m/ what happens? –  NickW Apr 15 '13 at 16:44
