IMAP doesn't work over low-speed connections

[Phil Shotton]

Binary package hint: thunderbird

The IMAP support over a low-speed connection is unusable. Running over mobile broadband (speedtest shows download bandwidth around 800kb/s and upload 600 kb/s with ping times around 80ms Thunderbird is unable to download mail larger than around 10k. It looks like the connection just times out; monitoring network activity there's a spike and then nothing, and TB just sits there. I can surf the web, browsing quite heavyweight pages but simply cannot use email at all even with only a small number of small messages waiting to be picked up.
On a high-speed connection everything is fine, but Thunderbird is just unusable as an email client while on the move.

Using Ubuntu 8.10 with a T-Mobile mobile broadband USB dongle, and Thunderbird version 2.0.0.19 (20090105)
