sendmail Planning Checklist

• What is the layout of your sendmail network? (domains, forwarders, relays)

• If you are using the /usr/etc/configmail script, do you have the values for the parameters you need to modify?

• If you are manually modifying the /etc/sendmail.cf file, do you have the values for the macros and classes you need to modify?

• Are you setting up any custom sendmail aliases? If you are, have aliases ready for the aliases database file.

• Are the /etc/hosts and /etc/passwd files up to date? The files should include the special relay station name for the mail forwarder, any station aliases, and user accounts for mail users, and so on. If you are using domain names, the /etc/hosts file should use the following format:

  ip_address fully_qualified_domain_name alias1, alias2, ...

  A common problem with sendmail is that administrators place the aliases before the fully qualified domain name in the /etc/hosts file.

• If you are using the Network Information Service (NIS) or BIND, are the sendmail-related files configured correctly (aliases, hosts, passwd)?
