Hi, I would like to know why a regular expression like '^(\[[^]]+\] *[Rr][Ee](\[[0-9]+\])?: *)|([Rr][Ee](\[[0-9]+\])?: *\[[^]]+\] *)(([Rr][Ee](\[[0-9]+\])?: *)?(\[[^]]+\] *)?)*' does not work in mutt. I tested it using perl and it worked perfectly matching the list and the Re: part of the subject.
Explaining the regex above, the (([Rr][Ee](\[[0-9]+\])?: *)?(\[[^]]+\] *)?)* part in the final matches any sequence of Re: and [list]. But I want it to be sure that it doesn't match just [list] because that would group two messages with the same subject, with no re: and not related. So I added the other part in the beginning. []s, Robson
