Re: [Dovecot] More effective mailbox fetching over high RTT link

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.

Is this a satellite phone question?

I build a bunch of products to help with this, but for a fairly specialist market. You can probably contact me offlist via this email address or any of them on the website below?

However, we use lots of compression, pipelining and some predictive fetches to wring every bit of performance out of a 2.4Kbit connection with 1.5s+ latency

Good luck
