Although still very much in "beta" phase, Gmail is already on its way to becoming a full-featured email client. For receiving mail it supports POP downloads from multiple mail accounts. APOP and IMAP have not been added yet, but APOP accounts can be utilized via a combination of fetchmail and a POP server (for instance qpopper) running on the local host.
fryke said:The bdegan link, I've tried. It works. It starts two local servers (pop and smtp) and actually seems to work - as long as you have the developer tools installed. It's quite ugly (the two servers must be running in your Dock), but it works. However: You might not actually _want_ that solution. The great thing about Gmail is its space and how you can organise mail by not having to organise it, really... I'm waiting for an official IMAP4-access by Gmail...
