I tried your patch. The first problem is that it doesn't apply. I had to
change the number 10 to 9 in the line above.

The second problem is that the value of from_addr doesn't (always?)
contain sender's addres. When I wanded to reply to this email with you
patch applied, I got: "On 2010-03-02, Michal Sojka wrote:". So I fixed
that in your patch and added removal of "" around name.

Previously, we would output:
'On Thu, 25 Feb 2010 14:32:54 +0100, Sebastian Spaeth <Sebastian at SSpaeth.de> wrote:' now it is:
'On 2010-02-25, Sebastian Spaeth wrote:'

In case we don't find a '<' (as indicator for 'Realname <email>'), we still use the whole from address.

Modified to use proper From header and strip "".
