Pull out recipient email before comparing with BCC
Pull out recipient email before comparing with BCC

Griddler removes "to" addresses from BCC so that its returned BCC value doesn't
contain the "to" addresses. However, when a "to" address is like "Ralph
<ralph@thoughtbot.com>", Griddler couldn't detect that it was the same as a BCC
address of "ralph@robot.com". Now it's smart enough to detect that.
