Matt,
I can find no such problem on my server from the same time period.
Test e-mail went through without hesitation. Gmail is very dynamic and you can
get rate-limited if you try to send mail that they consider spam. I regularly
flush gmail-bound mail that gmail has already rejected at least once so that it
doesn't contribute to my bounce rate. gmail servers usually reply with helpful
comments though.
