Can you clarify on what you mean by "character threshold greater than one in the subject header" ?

when you say mulitple occurrence of a character, do you mean a repeat like "testssss" where the "s" is repeating?

What is it about this subject, " this_is_a_hundred_percent_spam_header
" that you're trying to match?


I just wanted to know if it is possible to use the GUI to check for a character threshold greater than one in the subject header.

We are seeing subjects like: this_is_a_hundred_percent_spam_header

and would want to block this kind of messages.

Any idea?

thank you,

I'm not sure how to do it, but I'm guessing he's looking to look through the subjects for a certain number of underscores.

I think regular expression can filter such subjects:
to match 3 or more occurrences of letter_.

Usually I put these rules in a dictionary badsubj, use message filter below:

badsubj: if subject-dictionary-match("badsubj", 1) {
quarantine ("Policy");
