Subject: Mail File Format?

Hi,

Wondering if anyone knows where I can find the description
of the Mail files (/usr/spool/mail) format? Is it a RFC822 format?

I am curious to find out how PINE marks the each 
mail as read,new, and addressed? I opened the mail file
with an hex editor and didn't manage to see any difference
between a read and new mail.

Thanks

Way
