I’ve noticed a change in behavior in K-9 Mail v10 regarding the “Folder poll frequency” setting. Even if it’s set to “Never”, the app still fetches mail when I manually trigger mail check in the unified inbox (by swiping down). This results in receiving each message twice.
I’m using a multi-domain setup, and this issue did not exist in v9. Back then, manually checking mail in the unified mailbox only fetched one instance of each message.
Can anyone confirm if this is intended behavior in v10, or is it a bug that needs to be addressed in a future update? Is there any workaround for this?
Are you using Gmail and do you have the “all mail” folder set up to be shown in the inbox? That folder duplicates all mail, it’s a gmail-specific weirdness. Turn off that folder and all should work as expected
Thanks for the suggestion, but I’m not using Gmail. My setup uses a mail server provided by my ISP, configured as a multi-domain server — meaning accounts like xxx.xxx and yyy.yyy share the same backend infrastructure.
This results in each message appearing twice when I manually check mail via the unified inbox in K-9 v10. In v9, I could avoid this by setting “Folder poll frequency” for yyy.yyy to “Never” — even then, manually refreshing the unified inbox only fetched one copy of each message. In v10, this workaround no longer works — the manual refresh seems to override the “Never” setting, causing both accounts to fetch and show the same message.
So I’m wondering if this change in v10 is intended or a regression — and if there’s any new way to suppress mail checking for one of the domains during unified inbox refresh.
