What formats can you export emails and contacts in?

I currently use TBird. I do not like the direction they are taking it. What I particularly hate is there is no way to export your emails and contacts. I read that your program will import TBird emails and contacts (which TBird versions does this work for?) but what I want to know is what export format(s) do you support. I do not wish to trade one straight jacket for another.

Regards

You can import from all known TBird versions.
Emails can be exported to .eml format and contacts to .vcf and .csv formats.
