All of the old emails (from 2008 and older) have been saved by Mozilla Mail (and SeaMonkey Mail) as one file in a subfolder named, “Recieved”. I can also get to the mail folders named, “Sent” and “Drafts” ("…/[mozprofilestring]/Mail/Local Folders/Recieved" or Drafts, etc.). I can open these old folders as one text file and get the text I wanted. Trying to just open the folder within SeaMonkey Mail only gives me the text, and you cannot view the attachments.
So, it would be tedious to try and separate each and every email (a few hundred at least) contained within those folders (what would they be saved as anyway? .txt? .eml?) however, it’s easy to spot the attachments and I can just scroll down to them and select the base64 characters and copy that to the clipboard. I was hoping that it would just be a matter of pasting the clipboard contents into a converter to get the photo or pdf or doc or powerpoint attachment.
