my question is not directly mailscanner related, but I thinkt that on
this list I may get the best help.

Currently our students and employees have the same e-mail-domain
( and everything - sending, receiving e-mails, pop/imap
- is done by the same server.

We run Red Hat EL 5.4, sendmail, mailscanner, dovecot etc. on
one single server.

Recently we where faced with the situation, that some outsider
thought e-mails from students where official e-mails from employees.

Now I'd like to set up a system, so that all employees e-mail came from and all student e-mail came from

Is there some documentation on how to set this up? Is it possible to
change "only some settings"? Where to start? What do I need?

Thanks for any sugesstion or comment and best regards,
