If you've been expecting/waiting for an email from the server for some reason and haven't received it. I think I've solved the problem.
It looks like we had an upstream change in our SMTP relay that wasn't downwards communicated and it invalidated the Sender Policy Framework. Some domains
(e.g. Yahoo
) may have been selectively rejecting outbound mail as a result.
Please let us know if you experience problems
(
but please triple check your junk mail folders first!).
99.99% of
"your email doesn't work" is actually
"I didn't check my junk mail folder but decided to belligerently complain anyway"
I've resent the validation queue and all I am currently seeing are "bad destination email address" bounces, rather than SPF rejections.
