Searching Thunderbird emails & extracting information
 

I have a load of emails in my Thunderbird trash folder and some of them (all with a similar subject) I want to extract the email address for them and put in a text file. I have located the trash file but it seems that it is just a big flat file with a concatenation of all my emails in it, varying number of header lines etc etc - ie, something which really doesn't seem to suit awk, sed, grep etc.

Does anyone know of any way this might be accomplished, or any third party tools which may help?

I am not sure if there is any third party tool, but you will have to give some example data (obviously with any sensitive material removed) to make an educated
guess about what tools may help you.
