If you did not add a "message_size_limit = 0" to your exim.conf, i
highly doubt that you got that mail in that size. Exim has a build in
limit of 50MB message size.
The message could be increased in size while processing, i.e. due to
configuration mistakes in form of loops or external scripts.

But I have a limit which is what has me scratching my head.
mx1$ grep size exim.conf
message_size_limit = 50M
That is one impressively large spam email!
Do you have header_maxsize set?
header_maxsize total size of message header
You're also probably better off grepping "exim -bP" as that should give
you the running configuration in the unlikely event that the config file
isn't the one being used. (Damn you PHP and your zillions of php.ini files!)
If you do have message_size_limit and header_maxsize both set to
something sensible and you're still getting a multi-GB message, then you
may have found a bug.
The header comes from their system adding a single header for every
recipient they add to the email. I'm surprised that didn't kill the
sending system.
header_maxsize was not in my exim.conf. It is now.
mx1# grep size exim.conf
header_maxsize = 1M
message_size_limit = 50M
The spammer has not been back since I reported this, so I'll have to
wait and see if your suggestion fixes the issue.
Thanks,
Jack
