My accounts in Mail app stopped to sync post update

Same issue here, both iPhone and iPad updated to 18, inbound mail using imap from our own servers.

I did some investigation, and I find that the imap server drops the connection due to inactivity.

i guess something is seriously broken in a part where the start retrieval of message is skipped in the iOS 18 mail app.

The iOS version is not a required field, just leave it blank and make sure to choose "Bug Report" in the Feedback type.

It may take a while until all Apple pages have been updated with the latest additions for the new software versions.

Seeing the same, although a certificate that is signed by a private CA (that is otherwise trusted in iOS). The only workaround I have right now is to avoid IMAPS and fall-back to IMAP.

Practically, how did you do that? what settings on the phone mail app did you change to make that happen? I don't think my email server will talk to anything that doesn't request TLS, so I turned off SSL in the advanced settings for that mail account, and none of the authentication methods are supported -- MD5 challenge, etc all happen over SSL -- so I tried "Password", and then the mail app says no password provided (!)... there's 27 characters in the password field!!! I saved it and tried anyway -- it's not working so I am curious how you got that to work.

UPDATE: just to confirm... I tried with SSL turned off. nothing. I then went back to settings, turned SSL back on, and an saving those settings, the top of the settings sheet said "Verifying" and had a spinner, then green check marks appeared next to all my settings... So the settings sheet confirms that they can communicate, and that the phone and email server can establish communication... the problem is that the mail app doesn't fetch new mail from that same account

In my case I'm doing password auth (aka 'PLAIN' auth in IMAP) with SSL turned off, which my mail server supports. It's a horrible hack, but the only way I could make this work for now.

No e-mail either since IOS18:

Network error (POSIX 96)

(Before e-mail did not download from server without searching for own e-mail address. Something with ordering bug which was never fixed correctly. Now this workaround also doesn't work anymore)

noone from accounts are working.

test account - that also not working. but that was fully tested possible "connection issues" like certificate and so on. test shown clearly that all problem only inside app itself, as rfc IMAP are ok (A3 / A4 was sent in order but without waiting response of each. that is ok, but depend on "developer" how they implemented, next commands like FETCH are not issued by app)

Mail still not working on iOS 18.0.1.

It's a shame, since updating to iOs 18, my Mail is not working anymore on iPhone 15 Pro. Mail-Provider say that Apple is aware of the problem and they are working on it. But no solution in recent update. Please fix it!

Yo can do what you want - but that is not a login/connection issue.

simple developers faulted somewhere in code after login process. can see communication log from me in this thread - clearly seen that has been logged-in (ok), asked for folder statuses (ok). but not requested any from messages that are in Inbox (stuck in new "rotating of icon" = they indirectly saying "user need not more than new interface improvements in some rounded corners and so on" - that is tendence in app-development already many years exist).

I manage a few mail domains and several thousand customers.

We recommend that everyone download another Mail Client (e.g., Edison's E-Mail) from the App Store and use that. FInce the problem is solved, that's fine.

Hi,

I had a similar issue with my email disappearing from multiple accounts, and after troubleshooting, I discovered that the problem was related to my self-hosted IMAP mail service on Synology. After updating the SSL certificate, the issue was resolved, and all my emails reappeared. If you're using a self-hosted solution, I recommend checking your SSL certificate as well.

Hope this helps!

The Comcast (Xfinity) level 3 technician, a MacBook user, said that the problem is a synchronization issue. He said that there are YouTube videos explaining how to fix the problem by repeatedly setting up one’s client email account until you get lucky and the two systems synch. This can take many attempts. Until Apple releases the fix, using your ISP online email site is the only thing that can be done.

I’ve been facing this issue since updating to iOS 18. Has anyone found a resolution? The only workaround that seems to work is accessing iCloud Mail through a web browser, but the app itself fails to connect and gives a “Network Error (POSIX 61).”

Any suggestions would be appreciated!

Join the club. Mine has been doing that exactly. Until they fix it download the Edison Mail app. It's a free service where you can access all your email services in one place. Works great and it has no issues like we are experiencing with ios18.

Still waiting for a solution to the Apple Mail problem, nothing yet… just downloaded edison app and oh wonder: the mails get loaded again and it seems to work. So what takes Apple that long to give us a solution??

Described issue not directly with gmail, but with servers that apple use (they seems has proxy/or some sort MITM-servers that they trust and stealth use /as you can not check connection IP-s on GGL or MS - they has possibility to make MITM without warning/ ). and that behavior was already long time before current issue. (end-users warned about this possibility, but they has no concern about this - ok - their decision. can understand - "apfel" backup is done for "all" even if "not asked")

surelz apple says "all ok - not our fault" as "end-user" mostly can not check technical side of problem, but managers has to make "face of company" ... are other email-apps /can try any from many/ works ? so what that mean - google/ms/other or "apple-mail"?

example how to check:

/ outlook on windows-> +o365-> mails yearly backup with-deletion (for aproximation big amount 3 Months/900eml/1Gb ) -> look at mail on "apple" that shown email deleted only after 2 hours (wtf?) -> was done additional checking thru the web = all is clearly-deleted / == what can that mean ? = can suppose some proxying/use some servers "agreed" that has "low sync-rate" or similar.
