iOS 18 and IMAP, my findings but no solution

We use dovecot as IMAP server. The tests has been done on units that run iOS 18.1 or 18.1.1.

We had a few accounts that stopped working after upgrade while others had no problem. The accounts that still worked had no special characters in their password, only A-Z, a-z, 0-9.

I tried on one of the accounts that didn't work to change the password to the same basic ASCII format but that didn't help even after restart of both the mail server and the iPad. After deleting the mail account and doing a new setup on the iPad the error message that it couldn't connect to the server disappeared but it still didn't download any messages.

My temporary solution for the moment is to install Outlook on the units with problems that works.

We had the same problem with our dovecot server in the last days. In our case the problem was in a broken file in the home of the user ( where the mail folders are stored ). The filename had a newline char in. That file was there from 2002 so something has changed in the ios client. I suppose that some imap errors are now fatal for ios mail.

Great, excellent. Technology changes to accommodate grandma.

Still lousy mail management in my opinion.

I’m going to hold off on the 18.2 update l hear it hasn’t fixed anything for the majority of people

Thanks for your input I’m not updating until the mail issue is fixed.

And l wish they would’ve left photos alone too. Much better the old way not as many steps. And easier on my eyes
