iPhone 14 Pro Max, iOS 18
My 3rd party email imap account was not syncing on my iPhone. Specifically emails deleted on iPad or Mac Mini were not flowing through to my iPhone.
MY SOLUTION: Turn off private relay on my iPhone. I suspect hiding my IP address was causing the problem.
I hope this helps.

I've been dealing with this issue too since updating to iOS 18. While the only workaround I initially found was accessing iCloud Mail through a web browser (since the Mail app kept throwing a "Network Error (POSIX 61)" message), I finally found a solution that worked for me!
It turns out my VPN app was causing the issue by blocking communication with the Mail app. Here’s what fixed it:
After doing this, my Mail app started syncing properly again. Hopefully, this helps someone else out!
Same! At last.

After spending all morning with CC , I got it to work .
They had me :
-Erase all settings
Now it is working again but I have a long day ahead of me on iPhone and 2 iPads ....
I really hope this will help all of you too ;-))))
Noticed I was having this issue too. Found this thread. Decided to just try completely removing my Gmail account, the one that wasn’t syncing with the Mail App after the iOS 18 update.
I went into Settings — Mail App — Mail Accounts (it’s conveniently the very first thing at the top so easy to find) then selected the account that wasn’t syncing (Gmail, in my case) and then selected Delete Account. In the scary red lettering.
I was a little hesitant but went ahead and let it completely remove all the synced items from the account off of my iPhone. After a minute, it was removed so just went and re-added it and BOOM. Works like normal! No more issues.
(For reference, I use an iPhone 13 Pro with iOS 18)
I have just had a call with Apple support and the Engineer had me remove old (and not used for a number of years) VPN config on multiple devices after we demonstrated the issue and the issue looks to be resolved. Suspect some Apple Dev's have been lazy with some code in IOS18's mail.app and its causing the issue.
That's the point. Network communication is working. It's just a little bit technical, but we have an IMAP proxy that chooses from some different backend IMAP servers. If the user account ends up on an old IMAP server implementation (in that case f.i. a Cyrus imapd 2.4.17), IMAP Client of iOS 18 Mail app doesn't work. If the proxy directs requests to a newer IMAP server implementation (f.i Cyrus imapd 3.6.1), the iOS 18 Mail app works as expected, even the requests are handled by the same IMAP server proxy.
So it must be something in IMAP protocol handling on the old server that makes the iOS Mail app go out of sync or crash the syncing mechanism on the iOS device. Maybe some encoding behavior or just a different linefeed or something that has changed over the years...

restarts helps not. readding of acc helps not. full cleanup of ALL accounts is not a solution(and re-add even helps not).
that is not SSL related issue.
created temporary test account and forced imap server to "plain comm with exact device", pointed to local mail server and captured traffic. what can see:

that means that Mail app fully connected to server , asked for statuses, but not displaying anything.
Apple Broken communication for many business users ...
over ssl that surely goes encrypted but sucking at same point.
so only wait when some "smarties" from apple IT solve problem in app ... apple programmers use no CD/CI - simple sometimes update by "sales-manager requests", and without any critical-bug-checks ...
works not IMAP , google, icloud mails
offtopic:
also work not syncing in icloud-drive (there folders are "fully outdated" )
such is ios18.
@ingo2711 if you are referring to my comment --
I have deleted the account 20 times. I deleted the Apple Mail app from the phone, reinstalled from the App Store. it didn't help.
my comment about 3rd party email -- is a 3rd email app called Email - Edison Mail (from the App Store) I set up my mail accounts in the app and everything works as it should.
BTW - I never had the iOS 18 beta.

The issue is with the Apple mail app.
I've never had the iOS18 Beta installed,
Possible FIX
Hi, Fixed mine by overtyping the IMAP and SMTP Mail Server settings. Some corruption in one of the text boxes I think. Retype the Name : Password : Port, text lines in your Email client. Verify and Save.
If you can take a look at your mail server settings specifically the IMAP and SMTP. Make a note of the values and delete an overwrite them also check your passwords for both SMTP and IMAP. Make sure they are the same if you can’t see them look at the number of stars or dots. Look at the mail server settings boxes for password and port settings they’re the ones you need to delete and reapply.
Problem solved. My VPN was working in the background, even though the file was closed. I reopened the VPN and disconnected. AOL email came back to life.

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.

Very similar to what I see on my mail server's logs... the ios 18 and ipados 18 devices authenticate, TLS starts, and then the device never sends a request, so the server is sitting their picking its nose waiting for the device to ask it something, but it never does.
Meanwhile, the "connecting" or "Checking for mail..." just stays on the bottom status bar of the mail app.
At first, I was thinking it may be an issue with certificates, but it's not... I went to a bunch of online TLS tests and the mail server is fine and the certificates are trusted...
Plus, macOS is still retrieving the mail from that same email server just fine... this is squarely an ios/ipados 18 bug.
I also have the same problem.
With the new IOS 18 we have an abnormal behavior of the iPhone Mail App.
If I use different names for the incoming and outgoing mail server, I cannot configure the mail account correctly.
Let me explain further.
We are mail providers and have two types of mail management systems.
- An hosting system that uses one host such as MTA and MDA.
- Another system that uses different servers for MDA and MTA.
In the first case IOS 18 works well. To set up a mail account, we can set the same standard name “mail.mydomain.com” as the incoming and outgoing mail server.
This way I will use SSL encryption using ports 993 for imaps and 587 for smtps.
The problem occurs when we use different names for inbound and outbound servers (second type).
If I assign “imap.mydomain.com” as the incoming mail server and “smtp.mydomain.com” as the outgoing mail server, the Mail application will not allow SSL to work on port 993 and will only accept the unsecured connection on port 143.
This anomaly also occurs when using the hosting system (first type), using different names for inbound and outbound servers.
This problem does not occur on IOS 17 !!!
This problem is not present with IOS 18, but with a different Mail Client App
This problem have with Non-Beta IOS18

Having trawled through most of comments on this thread I did not see anybody mention what I observed:
I have the same problem since iOS 18 on an iPhone 14 Pro. I did not have the issue with iOS 18 on an older iPhone XR.
The way I can temporarily fix it after the refresh of the Mail app is stuck on the "Connecting..." is to properly terminate the app rather than simply swiping it away. On restart, the Mail app immediately refreshes properly and fetches new emails. A few hours later the same problem occurs and I have to restart the app.
Not sure what that means, why it works but only temporarily.
