ios 18 mail stuck in "checking for mail"

Since the first iOS 18, my IMAP account works just fine after setting up then a few hours later or sometimes a day later, it just gets stuck in "Checking for mail" when trying to update my inbox. Though I can access other folders just fine. And the unread count in inbox seems to be correct.

Uninstalling/Reinstalling the mail app fixes the problem for a while but it usually comes back. Though it seems that if it doesn't get stuck for a couple of days, the problem does not come back until the next OS update.

The IMAP account works just fine the Mail.app on macOS 14 and 15 , iOS 17. I really never had had an issue before iOS 18. I used the feedback form during the beta but it has not been addressed.

Any suggestions welcome

This did the trick. I use Pihole for ad blocking on my home network, adding these to the whitelist worked instantly.

Why does it use a "mask" domain though? It seems to be related to Mail's privacy protection feature. After disabling the "Hide IP address" option the query dor mask.icloud.com disappeared from my query log.

I don't know why it was enabled in the first place since I never enabled it and it was working fine prior to iOS 18.1 update.

I’ve just deleted and added my accounts again and it does the same thing

Somehow it works for me now, but it’s intermittent. So I don’t think I’m out of the woods, as I haven’t done anything different to fix it

Same issue on 18.2.1 with iPhone 16 and 14 pro max!
