For the first time ever, 7 of my (very much legitimate) automated messages sent to gmail users have bounced with this message:
Our system has detected that this message is likely unsolicited mail. To reduce the amount of spam sent to Gmail this message has been blocked. Please visit http://support.google.com/mail/bin/answer.py?hl=en&answer=188131 for more information. I will delve into that link, but is there an especially good method for avoiding this situation? - Grant
