Optimum server for mail apparently played havoc with my iMac mail app, kicking my Opt mail offline . Three hours on phone with both. Appears to be Optimum service issue. Had to restore all my mail preferences in Apple app to set that right. Working today
Last night, my Mac Mail app showed Optimum and gmail as offline and first I couldn't send any mail, then stopped receiving. Could sign in at Optimum server, but then that stopped responding. Was on the phone 4 hours, twice with Apple, twice with Optimum. Optimum maintained it was an Apple problem, but had me change my setup for mail in Mail App preferences on my Mac. Got it working and few mintues later out again. I called Apple again. We reset the preferences in mail app and agreed it was the Optimum Server causing problems.
This morning, I couldn't sign in to optimum webmail. Just testing it out, yet I could send mail from my mail apps, mobile and Mac. I didn't get mail that was sent to me last night but seems now it is working again and my preferences in Apple app, are as Apple set or reset them to work with Optimum.
Anyone else have this problem.
iMac, OS X Mountain Lion (10.8.2)
