IMAP, allow insecure authentication

I'm having a problem with Mail.app in High Sierra. In the advanced IMAP settings I need to set 'allow insecure authentication' but the setting is not saved. Because of this I can not make an IMAP connection. Is this a bug?

If it's a Gmail account you might need to set to allow insecure apps in Google Settings.

Found these comments by a user in my notes:

Called Apple Support.

When I called (chatted, really), they had me open KeyChain Access and search for "veri"

I went through each entry and deleted all the ones with a red warning (usually including "unauthorized" or "Unknown").

Then they had me restart and Google accounts started working again, and I could add new ones.

I did have to re-enter all the passwords, but it's not a bad as I feared it would be.

@polokov

sorry to bother u

concerning "3)" can u CONFIRM that Apple officially acknowledged it is a bug, and it is on the list to be fixed.

I had multiple phone conversations with a Apple care guy (see my posts) and this guy is really diving me nuts. If you can confirm, Apple officially acknowledged it is a bug, I consider terminate correspondence with this -sorry to say, unacceptable attitude in spite of his incapability- guy. If I continue, I'll probably get a heart attack or stroke soon... 😠
