sme is a mail server, as well as providing other services.
Other services can easily be disabled with commands.
I don't understand what your problem really is.
In what way is creating users on your sme server a problem ?
All users automatically have an email account.
With your "alternative" system, you would have to create an "email" user anyway, so how does creating a normal user really differ (time wise) from creating an email user only.
If you use Groups as intended, then the users will not have access to ibays, and in effect they will be email users only.
The user accounts can be configured to redirect email messages to other email addresses (eg external or internal addresses).
it would be easier for me to setup a email server at one location and have all email accounts at that one location.
This can be handled by the Delegate function where email for a certain domain (or domains) can be handled by another server or servers, see the Email FAQ
http://wiki.contribs.org/SME_Server:Documentation:FAQ#Internal_Mail_Serversone of the problems using the email server also is that you have to have administration rights to create users. i do not want to give anybody the power to be an administrator of the systems
Install the user manager contrib and limit access to selected server manager panels only for selected "admin level" users, logging in with their own username and password.
yum install smeserver-userpanel --enablerepo=smecontribs
i also do not understand why i should have to set up a user to create a email account.
That's how the underlying Linux system works.
You can create Pseudonyms or Groups which automatically have a email address.
Pseudonyms allow domain specific email addresses, but these of course must forward to a local user account, which can then forward to external or internal addresses if required.
accounts for
fax recepition
webpage recepiton
departments reception
main company reception
account that sends out email
vip accounts
general reception
special accounts where they are used for commuication with affliates.
As mentioned you can create Pseudonyms or Groups, which forward to existing users.
If you think creating those users is too time consuming or difficult, then I can assure you that the email accounts are not going to magically create themselves without some user input.
I'm not really clear as to what your problem is with management and creating users, it's very easy to do and with the user panel contrib you can have sub administrators doing the work without needing to give then full admin level access. Make all resources belong to different Groups and you can limit what Users then have access too ie many users have access to nothing as they are NOT members of any group.
I suggest you read the manuals for more information.
