Hello, this is....
From: will this be matched?
From how about this one?
---------------------------------end last message
So this is why I am not sure matching regex with "^From " is safe. It
will also match in the body.
As a tradition, when a mail is saved into mbox format, any leading "From"
line is prefixed with ">" as in your example.
I see, so mutt must not be using mbox format then because it does not do that.
Aha! I have just to learn that there are many implementations of mbox
and not all of them use From munge (the term for escaping from lines
in the body). For example, mboxcl2 does not and instead relies on use
of Content-Length:. Mystery is solved! Bad news is that I cannot use
the "^From " regex then. It is not safe for mboxcl2.
Kind regards,
Xu
