@richardd FYI, you may have dodged a bullet with ForwardMX. I signed up for the service after reading this post for an old domain of mine, updated MX records and everything properly with Zonomi (awesome nameserver service BTW). Only one email has come through at all, even to SPAM folder. After emailing ForwardMX, the reason is they seem to be being filtered by Google quite a bit, here is an excerpt from the logs sent to me by them:
"Our system has detected that this message is 550-5.7.1 likely suspicious due to the very low reputation of the sending 550-5.7.1 domain. To best protect our users from spam, the message has been 550-5.7.1 blocked."
I guess a lesson here might be to sign up for the service of a business we are considering purchasing and give it a test drive first. Maybe it works great for everyone else and I'm just having issues.
Any other recommendations for domain → gmail forwarding services? I still want that service.
I remember this business. Yes, I signed up for it as well just to test it out. I was getting sporadic results too. I could fix that problem by using a different domain for the mx forwarding servers, but it would be a pain with all the current customers. In the end, the ROI got to be too low for me, and having to fix those delivery problems.
I did research online for reviews. Trust Pilot is good place:
Do you agree with ForwardMX's TrustScore? Voice your opinion today and hear what 11 customers have already said.
Again, those issues could have been fixed, but the trouble wasn't worth it.
