If I understand you correctly you have more than one domain and you would like (e-mail address removed) to be a seperate user from (e-mail address removed).
If this is so, I don't know of anyway to do it in the GUI you have to do it by modifying the postfix config files.
This is easier than it may seem.
First delete all but the main domain that you have placed in the GUI mail server domains. So if your server is called foo.com delete out bloggs.com in the mail gui.
This will be replaced with a virtual domain.
You then need to open up the teminal app or use ssh to log into your server.
The files you need to modify are within the postfix directory which should be at /etc/postfix/
type in the terminal app as below:
cd /
cd /etc/postfix/
"this takes you to the postfix directory"
then type
ls
this gives you a listing of whats in the folder: there should be a file called 'virtual'.
now type:
sudo pico virtual
this launches a text editor called pico, you will be asked for a password, this will be your password if you are the administrator or it will require the root password.
The file will now open, read the file scroll down with the cursor keys.
at the end of the file enter in the email addresses and the user who should receive them.
ie
(e-mail address removed) user1_foo
(e-mail address removed) user1_blogg
(e-mail address removed) user2_foo
enter the email address as above using your own data then enter a couple of spaces then the short user name of the owner of the email...
once you have done this pres
ctrl and o and then return
This saves the file.
Then press
ctrl and x
This quits out of pico.
You now need to edit the main postfix config file.
Type
sudo pico main.cf
this will again ask for the admin/root password.
This is a large file, scroll all the way to the bottom of the file.
Then type in:
virtual_alias_domains = bloggs.com otherdomain.org
virtual_alias_maps = hash:/etc/postfix/virtual
the blogg.com otherdomain.org woulb be your domain names, you can enter as many as you have just seperate them with spaces as per the example above.
then key:
ctrl and x
to save the file
and
ctrl and o ( o not zero!)
now you need to let postfix know that it is to use virtual domains!
type:
sudo postmap /etc/postfix/virtual
again then enter your password.
now the last step.
type:
sudo postfix reload
this restarts the postfix system.
Now send some emails out to (e-mail address removed) and to (e-mail address removed) and they should now be accessed by different users as you have set up in the virtual file.
hope that helps, if you want to learn more about the Mac's email server "Postfix", I would suggest this book
