[Dovecot] More effective mailbox fetching over high RTT link

[Andrzej Adam Filip]

Could you offer some suggestion how to fetch mailbox content over 
high RTT link (with negligible packet loss)?

Currently I use IMAP+IDLE *but* it fails to use full available bandwidth
due to high RTT and "send command wait for response" nature of POP3 and
IMAP4 protocols.
