Mail not working on iPhone after iOS 18 Update

TLS 1.0 and TLS 1.1 are being deprecated due to security concerns: 

Security vulnerabilities

• TLS 1.0 and TLS 1.1 are vulnerable to a number of attacks, including POODLE, BEAST, CRIME, FREAK, and LOGJAM. These attacks can compromise encrypted communications and expose valuable data. 

• Compliance requirements

• Many organizations, including government agencies, must meet compliance requirements that mandate the use of TLS 1.2 or higher. 

• Evolving standards

• Internet standards and regulatory bodies are evolving to provide improved security. 

• Here are some details about the deprecation of TLS 1.0 and TLS 1.1: 

Windows

• TLS 1.0 and TLS 1.1 will be disabled by default in Windows 11 Insiders Preview and Windows Server Insiders Preview releases in 2024. This change applies to both client and server devices. 

• Azure

• Azure will remove support for TLS 1.0 and TLS 1.1 for new and existing storage accounts by October 31, 2024. 

• Internet Engineering Task Force (IETF)

• The IETF officially deprecated TLS 1.0 and TLS 1.1 in March 2021. The IETF recommends that companies, government agencies, and software developers use TLS 1.2 and TLS 1.3. 

While that is good info for people, This imap failure on the mail app on iOS and iPadOS 18 is happening on servers that use TLS 1.2 and 1.3

I found a solution: Spark mail …

using any third party mail app is not a solution- it’s not even a workaround. True, you get your mail, but the fact that all the third party imap clients work proves that something is wrong with the mail app itself

Is there a manual way to install that update? I don’t see it anywhere

Hey, are you still using in 2024 hotmail ???? LOL Try Securityfile Mail NO ads NO phone number No spam!

Does the new IOS 18.01 update fix the email issues?

It did not fix mine on my iPhone. No.

iOS 18.0.1 did not fix my mail issue.

Ok. I found the problem on my side!

The 2 accounts that where not working where using IMAP folders with some specials characters in their name.

No problem with iOS 17 and many years prior that. And no problem with other mail client ... but they makes the connection fails with iOS18.

After I renamed thoses folder (and changed all my setting on all my different clients...) ... it works again!

Millions of people have upgraded and not experienced this problem.

You might not have noticed the news today.

millions of Rogers network users in Canada did experience this issue. Plus there are numerous tech blogs bubbling about it.

It seems to me that TWO big regressions are active in this release - iOS mail client has some funky bugs with imap prefixes; and, there’s this fetch mail bug also.

the OP may well have a separate issue with the TLS 1.1, but this ios/ipados 18 mail app issue is growing and already pretty big.

apparently ipadOS is bricking iPad pros also. Thankfully, I didn’t experience that bug.

I have confirmed that my iphone with ios18 connects to the IMAP server (because it successfully fetches list of folders) with TLSv1.2, but still is unable to show any email messages.

I tried removing, rebooting and reconfiguring email account multiple times, without success.

OK, also here, IMAP stopped working on my Iphone after upgrade to IOS 18.

Ipad remained working on IOS 17.

Installing another mail client on the Iphone fixed the issue, clearly Apple changed something in their Mail app.

Had contact with customer support a few times, but what strikes me is that they are not aware of anything that changed!

I also used self signed certificate for years. After playing around for a while I decided to replace them with Let's Encrypt certificated.

Then it instantly started to work again and the error messages on the server side were gone, indicating the client had difficulties with the self-signed certificate.

So Apple, please fix the self-signed certificate support again and, AT LEAST, inform the public and your helpdesk people that something has changed so people like use are/can be informed.

Lacking information and transparency here is killing!

I updated to iOS 18.0 at the weekend and same thing has happened keep getting the message saying my password is incorrect even though it’s 100 percent correct. Any ideas what to do to fix? Or will there be another update to fix if Apple are aware?

Sadly it doesn't! I'm hoping when 18.1 finally comes out it will address this.

I personally tried everything so far. Deleted app, deleted accounts, readded them, erased iPhone, restored from backup, restore as new, forward slash, "INBOX", changing auth methods, changing push/fetch etc.

Nothing worked. And behaviour is the same as mostly everyone else. IMAP fails to fetch new emails despite SMTP working just fine. All my servers are my own work servers running on OSX 10.13.6 on Server 5.6.1. TLS is 1.2

MacOS is unaffected only iOS18 and 18.0.1 and also ofc iPad OS. iOS 17.7 still works just fine but Apple stopped signing those so hurrray for no ability to rollback either.

I am having the same issue. After upgrading to iOS 18, I am no longer able to receive emails to my Inbox. Interestingly enough, I do get receive mail in my Junk folder, and am able to send email. I just cannot receive email to my Inbox. I hope Apple fixes this soon.

I'm trying to help people who need that, but not like you, please ignore that, thank you.

No, you are trying to financially benefit from your spammy posts that do not in any way address the problem.

The service you keep promoting, Securityfile, is a rinkydink operation at which you are programmer, tester, etc. – that's what your profile said yesterday, before you deceptively changed it. Moreover, I personally would be concerned about its safety, given that I can't find any evidence of anyone using it, reviews, or anything to give me any comfort that it is even on the level.

Please stop. Your posts are unhelpful noise.

This is a partial update, since my problem is not yet solved.

I called Apple HelpDesk last Saturday as you indicated (thank you) and I passed 2 hours with them. They collected all the information I could give them. Then I was invited to reinitialise my phone (which is cumbersome, but no other solution than do what they want) and got an appointment for today at 12.00 (Paris time).

Note: this was a partial reinitialisation that did not put the phone back to factory settings (so I did not need a backup to restore it), but I had to reconfigure every app again. Credit cards are also deleted as well as ALL wifi passwords saved on the phone. (solution to it: go to the Passwords app, check the Wifi passwords stored there, save them somewhere else).

Today I had first on the phone a technician who after 30 min passed the call to an ‘upper level technician’. He (they all connect to your phone) did some actions on the phone (just to verify once again the problem and some settings) and collected some info via screen capture as well as the history of the phone. Next appointment is due for next Tuesday.

If you have the same problem with a second iPhone which was also updated to iOS 18, please mention it to them. It is an important information.
