Debian stable here, pretty sure it's unmodified,

Exim version 4.84 #3 built 17-Feb-2015 17:45:49

strangely, it works after HELO but fails after EHLO. did you do EHLO?
it may be the parameter parsing of the ESMTP mail command is splitting
on spaces too early.

In this case I'm supposed to be relaying for a fax machine that puts
a phone number (with spaces) in the local part of the retuyrn path.

The fax machine uses SMTP "HELO" and delivers the mail to server 1 (inbound)
server 1 tries to forward it to server 2 (relay) but server 1 uses
ESMTP "EHLO" and falls foul of this MAIL command parsing bug. generates a
bounce and then successfully delivers the bounce to server 2.
