This post was removed but I can't imagine why :-) They remove my posts fast, but wish they would address this issue just as quick. I have been an Apple guy my entire career spanning back to 1984. I have tried it all, and to no avail. What's really strange is that I I have 3 other IMAP accounts on the same device that work just fine. Just this one domain with issues. It's a very important account, and I am forced to use webmail if not near my MacBook Pro. That means no realtime alerts when mail arrives etc. The settings are IDENTICAL to my other imap accounts so any further trouble shooting seems pointless without Apple's guidance. But so far I have not seen one solution offered by Apple. Now, let me whine some more because it's a form of therapy art this point. I run the beta software and patched as recent as this morning 12/19/24. I hope with each patch that it will solve the issue but no. Somehow Apple seems to not care about the issue or its user urgency. This has been going on for a while now and only seems to have gotten worse. Works fine on the MacBook Pro, but the iPhone 15 is shit out of luck. I've deleted the account, re added it, rebooted and still the same persistent issue. Tried both / & \ in advanced settings, nope nope nope... Maybe it's time for an android and man I hate to say that, but Apple needs to address this mess. The designers choice of tools yet, Apple is dropping the ball on the support end. Please APPLE. This should be a slam dunk fix since you have been aware of it dating back a couple years. Help, please help!
