The perfect companion to Portable Thunderbird - Portable YPops!
For those not familar, YPops is an open source gateway to yahoo mail - it basically acts as a localhost POP server, allowing you to download your yahoo mail email into thunderbird, or whatever other pop3 client you are using. Very handy.
This forum from Mozillazine has more info on related systems for Hotmail etc etc, many of which could also be candidates for portablisation.

An other one is Html2Pop3: it is a virtual POP3, SMTP and NNTP server and allows you to get mail from an Yahoo account, or Hotmail as well.

Or you can use the Webmail extension. It just won't work with Thunderbird 1.0.7 due to a bug. It works with 1.0.6 and 1.5 RC1, though.
Sometimes, the impossible can become possible, if you're awesome!
I think FreePOPs is the best. Can be a portable app.

I'm a fan of the FreePOPs and Portable Thunderbird culmination.
