We'll be jumping from 7 to 12.  I've read the docs and it seems straight forward.  One question, the install path.  The default path was not used on this install.  Smartermail is installed on a drive lettered E.  The directory tree looks sort of like this:

 

E:\

--MRS

--Service

--SmarterMail

    --Domains

    --ImapRetrieval

    --Logs

    --PopRetrieval

    --Spool

--Web Server

 

What I can't figure out is if the install path was simply E:\, or if it was E:\SmarterMail.  Any ideas?
