One of the thank-you notes I sent out to a donor last night bounced, with the message: “Domain of sender address does not exist”. Which is strange, because the domain chromatism.net most certainly does exist. I’ve exchanged emails with this donor in the past, so something is screwy here.
Our generous benefactor lives in Wales. Maybe his Welsh provider has blocked the domain for some unknown reason.
Anyway, if you live in Wales, and didn’t get a thank-you note for your gift, that’s why. I’ll just have to say “thank you!” from here.
