iphone mail app suddenly fails to connect to imap mail servers
The default iphone mail app was working fine with my gmail and yahoo accounts. Yesterday afternoon I started getting errors syncing emails with "connection to server failed, network error posix 61" errors. Network was working fine. I tried (in order) hard phone reset, turning off and on mail server in mail settings for each account, deleting and readding the accounts, without any success. I upgraded to IOS 18.3 last night. After upgrading I still have the same error. The yahoo and gmail specific apps work fine. I had gotten used to the IOS mail app. Any idea on why mail doesn't like imap servers anymore? Are there any next steps besides abandoning the mail app and using something different?
