Rated 5 out of 5 stars

GMM is still not working for any of the fifteen GMail accounts I monitor, so I only hope that FrasierCrane's post indicates that they have started rectifying their mail servers in turn and would shortly fix this issue.

I'm also a bit surprised that Todd Long has been completely silent on this issue. He would, at least, know exactly what is causing this and whether the fix is on his side or Gmail's.

And no, it has NOTHING whatsoever to do with OpenDNS settings ... irrespective of what Jade J'adore and MarcoSarto have posted. IF (and that's a BIG if), GMM has worked after changing your DNS settings to OpenDNS, then it must only be a coincidence of "their" server getting fixed as FrasierCrane's was.
