Also forgot to mention that you need to preserve permissions.  I had downloaded the dir to my computer and uploaded to the original directory.  This overwrote the permissions.  So it is better to copy/rsync it from the  server itself to preserve all the unique permissions on each folder. 
For example
find /usr/local/surgemail/archive_deleted/$domainname | grep -r  "$username"
rsync -av --delete-during --progress --stats /usr/local/surgemail/archive_deleted/domain.name.com/ra/gd/username/ /var/surgemail/domain.name.com/ra/gd/username
I'm thinking of making a script that will ask you for the account name, domain name and just run something like 
1) Enter username
2) Enter domain name
3) Do you want to recover the $username mailbox from $archive_location (/usr/local/surgemail/archive_deleted/domain.name.com/ra/gd/username/) ?  Y/N
Would be cool if it already came included with Surgemail :)

        Any chance of automating this in the future in the UI?
        
       
    
    
    We may do.

              Ok so I've been removing old accounts and I do have
                archive_deleted enabled so the accounts are still
                there.  I've just never needed to recover any before.  
              
              
              
              A grep later I found the subdirectory that has the
                account (why you guys use all these random lettered
                directories I'll never know). 
              
             
          
          
          Yeah I hate those too, but It's fairly critical for
          performance on some file systems and it's easier if it's
          always used even when not critical.  
          
          
            
              
              
              I cannot find any documentation on the website for
                how to physically recover this account from
                archive_deleted folder.  
              
              
              
              Anyone willing to help?  Would I just create the new
                account, find the new dirs and copy the data in? 
              
             
          
          
          Yes, that's it.
