well, the use-case is more a users-paranoia-reason :) We have some
customers that defined a lot (the winner is 2800) of email addresses to
filter; we were doing it via procmail rules, but now we're moving to
consolidate everything inside exim via user filters.
We started with one rule per address, but it's making our db backend
crying :) so we decided to create rules with 100 addresses in it (and we
do a <current sender> matches <regexp with 100 addresses>) but then we
are facing the limit of the original message.
am I getting right what the limit of 1024 is not for the whole text of
the rule but for a single line in it? is there some "smart" way to split
into several lines a regexp match? something like
if $sender_address matches "addr1@???|addr2@???|
addr3@???|.....) then ...
