With the rise of bitcoin blackmail spam it'd be nice to have a rule to match
bitcoin addresses. The regex is ^[13][a-km-zA-HJ-NP-Z1-9]{25,34}$

--- Comment #1 from Kevin A. McGrail <km...@apache.org> ---
BTC has just as many legitimate emails as the issue you point out.  The rule
might be useful in meta but otherwise pointless.

I'd suggest discussing on the .users@ or dev@spamassassin.apache.org mailing
lists.

Perhaps someone can help you create a rule to install locally and you can
discuss the efficacy.

Regards,
KAM

James, since you yourself provided an actual regex to match bitcoin addresses,
constructing a SA rule from it is straight forward, using word boundaries (and
maybe an optional bitcoin: protocol prefix) instead of the begin and end
anchors.

A bitcoin address in an email is not inherently spammy or otherwise
illegitimate. Unless such a rule (by itself or as a meta-rule's sub-rule) is
beneficial, there is no point in adding it.

Closing RESOLVED INVALID, aka NOTABUG. Leaving implementation of a bitcoin
address sub-rule to whoever actually needs it first in rules.
