Huh ?

[...]
1888 (97%) messages were gated through Gmail's Primary mail server
(gmail-smtp-in.l.google.com).
gmail-smtp-in.l.google.com is at least two machines, but much more likely to be at least two clusters of machines ... :

gmail-smtp-in.l.google.com. 232 IN A 64.233.185.27
gmail-smtp-in.l.google.com. 232 IN A 64.233.185.114


.. load-balanced in some way. One MX record doesn't mean one machine and no load-balancing by any means.
