Email sorting via IMAP

[DarkSide]

Hello again all,

One of the users on my ISPCP installation uses IMAP via his iPhone to access his email. He has set filters in the webmail interface of ISPCP to sort his emails into various folders. If he logs into the webmail interface then it will sort the emails as expected, however if he receives *new* email and then accesses via his iPhone then they are not sorted into the relevant folders until he logs back into webmail (this happens instantly if he does).

Is there anything I can do to solve this "issue"? I was thinking some sort of cron job?

Thanks all,
Paul.
