iOS not syncing email over IMAP

readyfireaim

Hello,

When I login with SOGo I can see all of my emails. Same with other IMAP clients, but when I login with iOS I don’t see all of my email. If I search for recent emails they show up in the results and then will show up in the list of emails. I’ve tried deleting the account and re-adding, reboot, restarting the mail app, but nothing has seemed to work. I don’t see any error messages in the logging.

Even if I mark all of the “missing” emails as unread they still don’t show up in iOS.

Anything else to try?

Thansk!

How many days is iOS syncing?

esackbauer I’m seeing it sync about 36 hours back, then no email, then starting mid-day June 22, 2023 and from there way back into 2022. The missing emails are “rolling.” They seem to age out after about 36 hours. I get them and they show up and then they disappear.

Go to your Mailcow details under iOS -> Configuration -> Mail -> Accounts -> Your Mailcow
and change the synchronisation period as you wish, but be careful if you choose to sync more than one month, because this could affect the performance of your Cow and/or the whole server (depending on processor power and RAM).

I did some screenshots of my phone (sorry, it’s in German, but you will easily understand).

Try to not use IMAP, but Activesync (Exchange Server) instead. I have no issues with ActiveSync on my iPad.

I can try that. What’s weird is this is just one of 6 IMAP accounts, but its the only one with this issue.

[unknown] Activesync doesn’t show any emails after that same June 22, 2023 date that IMAP is choking on. This is definitely something server-side.

Is there an easy way to delete the dovecot cache files? I assume the issue is there.
