Hello list,

I implemented BATV in my exim-installation like it is described in
this thread: http://www.exim-users.org/forums/showthread.php?t=51895
I also tried the method described in the official exim-book, but I get
the same results.

As far as I can tell it works flawless until it comes to senders which
include uppercase letters.
Let me show you this example.

A you can see in the last line, <[EMAIL PROTECTED]>
has uppercase letters in it.

Here is the header of the mail:

I'm not totally sure if the uppercase letters are the only problem,
but it seems to be the only pattern that matches.
There are hundreds of other mail which don't generate such errors.

Has anyone out there a clue about this?

Many thanks in advance,
tropfstein
