[Exim] odd error....

I received an e-mail with an odd error message...

<lormar@???>: host mail.labnet.com[205.238.148.10] said: 550
Syntax
error in 'From' header: malformed address: <cdaehn@???>\n may not
follow cdaehn@??? : failing address is: cdaehn@???
<cdaehn@???>

I'm sure it has to do with my "headers_check_syntax = true" entry in the
conf file... But is there any way to make it less strict? This is a
pretty silly error.

The original header contained the line "From: cdaehn@???
<cdaehn@???>" and exim rejected it. *shrug* By the way, I'm
running v3.22 because that seems to be the only one I can get to compile
and run correctly on my machine. 3.33 compiles, installs, then crashes
every time I run it, and 3.36 errors out while trying to compile...
Gotta love Mandrake sometimes. ;-) Perhaps I should submit that to them
as a bug.
