37.16. Summary

After completing this chapter, you should be familiar with the concepts behind Internet email, the protocols used to transport it, and the types of programs that use them. You should also understand what tasks Sendmail performs, and how it can be configured to redirect email with aliases, limit the addresses from or domains to which email is forwarded, and support multiple virtual domains. The use of Webmin's Sendmail module for reading users' email and viewing the mail queue should also be clear. Finally, if necessary, you should know how the module can be set up to grant limited access to a Webmin user so that he can manage only a subset of the email domains hosted on your system.
