my wife is running a pixi with T-Mobile Sim card.

It is not possible to fetch EMail from her IMAP-Server, once in a while one mail arrives but most of the times just nothing happens.
When she activates WLAN and uses our home DSL all works fine (so it can't be the configuration).
When she uses my O2-Simcard (other provider) all works fine as well.

With Terminal (the homebrew stuff is great, thank you all for doing this!) I found out that the RTT to her IMAP server are 600 ms and more over UMTS and 40-120 ms with WLAN....well...this must be the key.

Is it possible to change/patch the timeout settings for the Pixi EMail program?

Any help is appreciated
