Anyway, I'm not sure the search terms I can choose from will help here - what I really need is "received today" or maybe received in the last 7 days. Is this possible? If not, maybe an enhancement? Yes, good point. This is a good candidate for an enhancement request. See ~~Bug 3438~~.

Thanks a lot for your thoughts. I decided to follow your advice on setting up a virtual folder. One seems to have appeared anyway called "Virtual Inbox" which I haven't seen before. I've just upgraded to 4.1-RC2, so maybe this is a new feature? It seems to contain unread messages.

At the moment, I need to specify a particular date, which will work today, but presumably tomorrow will then contain yesterday's messages?

I suddenly had a thought today, and wondered if I could instead use the Search interface to just retrieve messages in my inbox which were received today - this is working beautifully. If this works better for you, then you should save this search as a virtual folder and then set this virtual folder as your default folder in the preferences. This has got me wondering about the way IMP interfaces with IMAP. Could it be a configuration option to only fetch the last page-worth of messages when accessing an IMAP folder? No - because in order to determine the last page of messages in an IMAP folder, we have to know the order of all messages in the folder. To do this requires a search command on the IMAP server - a potentially expensive call depending on your mailbox structure, your IMAP server speed, your IMAP server I/O speed, and the # of messages in the mailbox. You've also enabled the 'sort_limit' configuration option, correct? My assumption from the above behaviour is that at present all headers are retrieved This assumption would be incorrect. but (obviously) only a single page-worth of headers are displayed at any one time. My suggestion might also be quite a performance improvement. If you want performance improvement, try CVS and its full mailbox caching capabilities.

This is a bit vague, but a point worth raising I hope. I use IMP as a way of accessing my personal IMAP account through a work firewall - all commercial webmail interfaces get blocked by surf-control or similar. I have recently been having problems accessing my account - the browser session has been timing out, and I now think this is due to the number of messages in my inbox (around 700).
