Here is a real mystery.

I have several Email accounts in Apple Mail, which I use here at work and also at home. Out of the blue, starting after 10:00 a.m. yesterday, the two accounts I have through my primary Email provider (Armstrong Zoom) won't send mail anywhere. The Emails I compose end up in my Sent folder, I don't get any bounceback messages, and yet the recipients never receive them.

I have verified this by sending from these accounts to others I receive in Apple Mail (e.g., my work account and gMail).

If I Email from home or from my Blackberry using these accounts, it works just fine. It also works from Zoom's online interface.

After verifying that all my settings are correct (and after all, I had done nothing to change any of them), Armstrong technical support could only suggest that I delete the account in Apple Mail and set it up again, which I did. No change.

I can't identify any other change made yesterday after 10:00 a.m. that could have caused this to happen.

Does anyone have any ideas as to what could be going on?

Thank you in advance.

It's only failing at work? Same machine being moved from home to work, or a different machine at each location? Superficially, the most likely answer would seem to me to be that at work you're running afoul of some kind of filter or proxy.

Two different machines.

...and what do you know? Tested this morning, and everything is working normally again! I hadn't changed anything before the problem cropped up, and when I deleted the account yesterday from Apple Mail and put it back in again, it didn't solve the problem. (I had also restarted my iMac in the process of doing this, too. Again, the problem persisted.)

At the end of the work day yesterday, the problem was still there. Today, it's magically gone. Go figure!

I think you should change your outgoing mail server to your ISP's SMTP server. And yeah turn your authentication off. I hope it will work!
