I have tried both mail and Thunderbird. mail of course doesn't work 
because it read from /var/spool/mail while postfix puts the email in 
Maildir. However I would have thought that I could download the emails 
with Thunderbird (on my laptop).

I hope you're not saying I have to install procmail too. I'd like to 
keep the system as simple as possible: postfix, dovecot, squirrelmail 
and majordomo (later) are enough.
