We have all homedirecories, e.g.
//server/home/company/last_name/
this
path would like %homepath% in Windows (for each user), and after the
homepath is the pmail-folder with the mails. (also %homepath%\pmail\ )
Also we only need some variable which does the same like %homepath% in windows
The mailbox directories in Mercury must be in the same location, i.e. \\server\home\company\last_name\pmail so the only variable you can use the the ~8 or ~n in the place of the last_name. If you have multiple paths to different servers and directories them that means each of these must be managed by their own Mercury/32 installation.
I'm not even positive you can still use the \\server\home\company\~n\pmail format for the mailbox directory spec since it is not really officially supported except with NDS in a Netware setup. I have used it in the past and it did work for me but I've not used it in at least a couple of years.
