Seriously, you shouldn't be asking that question. The fundamental flaw
here is in the assumption that an all-number mailbox user ID is virtually
certain to be spam. It is not. Clearly, the default score assignment to
that rule is too high.
Well, firstly, the rule name says "STARTS" with nums. That would imply
that the original condition for which this rule was created was NOT an
'all numeric' user part, but perhaps some 'jumble' of characters that
merely *starts* with numbers.
I would PROPOSE (to those with a nice testing rig) that the rule be
modified so that there has to be at least one non-numeric character after
the initial first 6 digits.... ie. /^\d{6,}\S*[^\d\s]\S*@/
This will reduce the 'hits' on phone numbers, while possibly still hitting
the 'bad' usernames that it was intended to hit?
