I don't usually subscribe to threads but have to one (the USB-C one) just the other day.

My email is on a personal Google Apps account so basically the same as Gmail.

Some (not all) of the subscription thread emails from the one topic are being tagged as spam by Gmail



I see the from address is "andy at ...." rather than something like "noreplyatempegbbsdotcom"

I presume an SPF record might fix this but also perhaps better to use the forums domain as the from address too? It's not critical but I thought it would be worth mentioning. I presume private messages would have similar results.
