Well, ok, I'm an idiot. Silly me assuming PIPELINING was working...
until I manually connected, issued a CAPA and got ERR back. Lovely.
Sometimes capa changes after auth, so you could check that, but if things are so slow it's probably not there.
No PIPELINING pop3, no concurrent IMAP connections. Jeesh. Time to
change hosting providers.
Oops.  They're probably using the uw-imapd stuff, which is pretty poor.

[Since I'm going to be moving to a box that I'm going to be sysadmining,
I'd like to ask, in your experience, what is a reliable pop3 server
would be to select?]
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.
