Sometimes capa changes after auth, so you could check that, but if things are so slow it's probably not there.

Oops.  They're probably using the uw-imapd stuff, which is pretty poor.

We use the courier one which does pipelining, but its imap isn't that hot.  Well, it works enough, but the 'rev1' part of 'imap4 rev 1' doesn't really work so we hardcode evolution to use imap 4 instead against courier.  Cyrus imapd has a lot of features and imap extensions, but beyond that i've not used it much.  Then there are more modern ones i'm too old to know much about ;-).  If you're just using pop + no keep on server, then just about anything will do.

You could also try this patch, most pop servers support pipelining implicitly, due to the simplicity of the protocol, even if they don't advertise the fact.
