It's in the regexp. You didn't protect the leading slash, so procmail
interprets \< as
\ end of whitespace
< literal left-side angle bracket
...
Solution: protect the leading slash ...
* 1^0 B ?? \\<((minolta|maxxum|the).*[579]|(xt|50[05])si)\>
or with an empty pair of parentheses (as most of us do it):
* 1^0 B ?? ()\<((minolta|maxxum|the).*[579]|(xt|50[05])si)\>
thank you david. now i remember that something on the same lines
was mentioned in past in a thread about "MATCH and \/".
it would be swell if the point about protecting the backslash -- as
noted above -- makes into the procmailrc(5). as procmailrc(5)
suggests that...
Conditions start with a leading `*', everything after that
character is passed on to the internal egrep literally,
except for leading and trailing whitespace. These regular
expressions are completely compatible to the normal
egrep(1) extended regular expressions. See also Extended
regular expressions.
...and the regex otherwise works perfectly w/ regular/external
egrep (on freebsd).
On a separate note it's much better to use 2147483647^0 than 1^0
as the weight when all you're doing is trying to coax procmail
into ORing instead of ANDing, but that's not what you asked about.
i separated the regular expressions for testing. i was initially
planning to create just one body match condition, but some of the
regexps are too cumbersome as it is, i will leave them separated.
and, yes i do use 2147483647^0 in other recipes which are pure, or
almost pure, OR's. thanks for the reminder though.
