Dovecot 0.99.x isn't very good or fast POP3 server. 1.0-tests are a
_lot_ faster. 0.99.x actually locks/unlocks the mbox file separately for
each mail that is read.

Look at the network traffic between Dovecot and Evolution. Does it pause
somewhere for a long time?

It may be an authentication problem, Dovecot advertised AUTH=PLAIN but
if client actually tried to use it it didn't work correctly. 0.99.13
fixed this. Maybe it helps.
