Aye aye, cap'n :-)

It will recreate the outbound queue file if the message has changed at 
all, otherwise it should just copy the spool file.

I think that's a red herring. I don't think I *ever* measure the length 
of the email address.
People who don't know the term should read this:

(That's for the benefit of the many people on this list for whom English 
is not their first, or even second, language. :-)

Is this just in the outbound queue file, or also in the inbound file 
and/or in any quarantine file created?

As I said, I think that's a red herring.

It sounds like it may well be a bug. I'll take a look in the Exim code 
and work out a fix for you. It needs to go in all the output copies of 
the original, as the message should end with a proper line termination 
sequence.
