If the From: header contains a punctuation character immediately prior to the @ character in the email address, the blacklist mechanism breaks down. For example, assume the user has:

    blacklist_from [EMAIL PROTECTED]

If sent mail with a From address of something like:

    [EMAIL PROTECTED]

the message won't be marked with USER_IN_BLACKLIST:

If the punctuation character is not the last character prior to the @, the blacklist mechanism appears to work:

The precise character used doesn't seem to matter - if it isn't alphanumeric, a hyphen, or an underscore, SA seems to get confused.

Fortune Documents the Great Legal Decisions:

We think that we may take judicial notice of the fact that the term "bitch"
may imply some feeling of endearment when applied to a female of the canine
species but that it is seldom, if ever, so used when applied to a female
of the human race. Coming as it did, reasonably close on the heels of two
revolver shots directed at the person of whom it was probably used, we think
it carries every reasonable implication of ill-will toward that person.
