A great feature was an extension to KMail, which could be run by any user (not having root permissions) after internet dialup (via KPPP or KInternet) and then downloads the mails for all users using KMail and processes them into their proper maildirs and mbox files. (Sure, this is already possible using the common tools like fetchmail, but my intension is that it succeeds simply to put the tools name like "/opt/kde3/bin/kmailget -a" into the "run after dialup" field of KPPP / KInternet; and the tool by itself collects the proper configuration settings from all unique users and peroforms an overall download. By default the tool should display a status window which apperars on all desktops but is kept in background.) I.m.h.o. a good way to go for the work of such a program would be:
a) Collect the users' KMail configuration data
b) synchronous request to all mail servers for the unique accounts' states
c) calculation of the overall download amount (for progress bar)
d) download the mail (or synchronize the offline-IMAPs) in respect to the unique users' POP3-filters and "common" filters (for sorting).
[Alternatively it could be a way that the tool just downloads the mails and puts them into a central storage, such as ~/Mail/inbox/new/; and processing the filters will be done when the user in question starts his own KMail session.]
