I'm trying to use a more generic approach for some patterns to handle mailing list, e.g., something like:
save-hook "~C ietf-\\([a-z0-9]+\\)@ietf.org" =%1 instead of having one entry for each mailing list. Is that possible with the current mutt features? It seems that back-references in regular expressions can only be used for "spam": spam pattern format ... format can be any static text, but it also can include back-references from the pattern expression. If that's the case, would it be useful to extend it to other (all) uses?
