emacs, speechD-el, and migrating e-mail from Evolution or Thunderbird

[Fernando]

Hi everyone,

Is anybody aware of a guide for someone interested in migrating his/her
email from Thunderbird or Evolution to Emacs?

I have not been able to find any guide or how-to page so far.  I suspect
Emacs has more than one e-mail client and, if that is the case, I would
also really welcome a recommendation for the best one to use with
SpeechD-El.

Lastly, would the recommended installation order be the following?

first, getting speech dispatcher setup with ALSA and making sure all is ok
with Orca;
Second, installing Emacs;
third, installing SpeechD-el.

My machine has Ubuntu 8.10 and Orca, eSpeak, and ALSA seem to be already
working well together.

Thanks,

Fernando
