All emails not shown

K-9-mail updated to the latest version but one account (imap) is failing to show any messages on my phone but the tablet with the same version is showing all the emails as I would expect, also I can’t see how to check network settings to ensure the settings are correct.

The outgoing mail server settings are under an account’s “fetching mail/incoming server” settings.

Thanks for your reply, I managed to find the settings after rooting around but it was just a case of resetting the sync options to sync emails from more than one day, although I am now looking at where to find the ‘push’ settings, my tablet immediately comes up with the option to enable/disable it but not my phone for some strange reason.

Thanks that solved it, easier than I thought it would be.
