Subject: mutt should not replicate ">From " headers while bouncing
Date: Tue, 1 May 2001 10:38:55 +0200
When delevering mail using procmail, in some cases procmail generates
new "From " headers and `escapes' the old From headers with an '>', like
this:
From bas@xxxxxxxxxxx Mon Apr 02 09:30:39 2001
>From bas Mon Apr 2 09:30:39 2001
Received: from localhost ([127.0.0.1])
Now, the problem is that when you bounce such a message in mutt, mutt
feeds this escaped header to sendmail (exim in my case), which
chokes on it, and interpretes the > as the beginning of the body. This
results in a mutilated message being recieved.
This could very well be a bug in exim or procmail, but here is a simple
workaround patch for mutt. The diff is against 1.2.5, but should also
work with recent versions.
