We're at a loss as to what to do so, any advice will be gratefully received.
One thing that can get you labeled a spammer is when the mail server sending the message doesn't match a DNS lookup of the domain in its From: address. I've found that digests are substantially more likely to get delivered than individual emails, and I suspect that's why.?I'm not suggesting this will completely eliminate the occasional delivery problem but it's highly unlikely that a 500-level error will be thrown.
Honestly, to this point we've done nothing to refute Google's assertion that these messages "look like spam!"?To provide more helpful advice it would be nice to know exactly what was in the messages that GMail didn't deliver.?
