Looking back, I did modify the report post to only e-mail me in early September.

What's frustrating is that the bulk of what would irritate GMail servers happened early in this year. I would have hoped the decline in e-mail would have cleared it up. I don't even know where to start to try and contact someone at Google, nor do I have any faith any attempt to do so would lead anywhere.

Their web page does have a number of suggestions for bulk e-mail senders. Problem is, this site really isn't a bulk e-mail sender. Having any sort of clarity on why it was flagged would help me resolve things. The e-mail to a friend didn't have anything suspicious in it to my eyes. And the same e-mail went through fine when I sent it via my iCloud account, instead of my personal domain.

I may migrate to someone else to host my personal mail. Problem is doing so will require me to change my way of using e-mail entirely. More things to ponder when mythical time to do so appears
