Effective anti-spam add-on for Thunderbird?

[plazma]

Can anyone recommend a good add-on for Thunderbird? I have a spam problem.

run your pop mail thru your gmail account and let gmail do the filtering.
if you're unsure how to do that send me a pm.
you can masquerade by adding identities in thunderbird for your gmail accounts.
