If you are thinking of upgrading to IOS 18, you may want to hold off as there is a bug in the mail application. You may be able to work around this by adding just a ‘/’ for the mail path and you mail not.
If you have already upgraded to IOS 18, you can use webmail on our website (under web apps) to access e-mail IF the ‘/’ fix does not work for you. Here are the contents of a ticket sans user info:
The mail app on my iPhone and iPad stopped working a few days ago. My subscription expires on 10/5, so I need to know if this is a fixable problem. I reloaded the app several times with all the correct info (below). It returns the following error messages: Updated Just Now Account Error: Eskimo. Cannot Get Mail The mail server "mail.eskimo.com" is not responding. Verify that you have entered the correct account info in Mail settings. Server message "Mailbox doesn't exist: mboxes/buy/ebay/guns/s&wjframegrips"' -------------------------------- I checked and the referenced file does exist. I also reloaded the app several times with all the correct info: Incoming mail server Host name: mail.eskimo.com Outgoing mail server SMTP - mail.eskimo.com Primary server - mail.eskimo.com Host name - mail.eskimo.com Use SSL - On Authentication - Password Server port - 465
It turns out this is a bug introduced into IOS and IpadOS 18 mail app. One user has found that by adding a / to the path (initially a null path) it made it work for them.
