You can't use a regex to parse it. Instead use one of the available mbox parsers out there, e.g [2].

If you're looking for the start of messages, you should be searching for lines starting with "From ", including the trailing space. Lines starting with "From:" do not delimit messages in mbox format, but lines starting with "From " in the body of a message should be escaped. Hope this helps. Best Regards, Jeff

I indeed missed this important detail! Kind regards, Xu

So the term is "From munge". So I guess the format of mbox that mutt uses does not from munge. it must be then than that the format mboxcl2 is being used, which does not from munge and relies on Content-Length:. Can anyone confirm? I searched for mboxcl2 in man muttrc but no instance. Kind regards, Xu
