Solutions for slow pop3 / imap?


Would like to seek the advise of the experts here.

Majority of my users are affected by the slow internet access as a result of the Taiwan earthquake. As a result, mail download is very slow, sometimes even leading to timeout errors.

Most of them are using Outlook. I also noticed that sometimes, they click on the send/receive and outlook then opens another connection, possibly aggravating the problem.

Even webmail is affected.

I would appreciate any suggestion to try to ease the pain.
