Sure. Yeah I know NM is like that and it works that way on my other Nokia's with no other e-mail clients.

But the N900 is running Modest and NM is a "plug-in". In my implementation I have 3 POP accounts that are not set up via NM (since I need to keep more then 30 days of messages in my iinbox). I would have assumed that since the N900 has such strong multi-tasking capabilities that the outbox would be able to multi-thread/task the outbox function to increase the performance of e-mail sending (currently it is serial -FIFO- and if one message gets hung up the others wait) . This may be one of the reasons that people have been reporting issues with e-mail sending?

I will have to test if uninstalling NM will seperate the inboxes. Anyone have Multi Pops/imaps set up without NM that can check this?
