Define the MANPATH Environment
A MANPATH environment variable, if present, should avoid references to non-local
directories.
sendmail Configuration
Edit the sendmail files if you use more than one kind of mail user interface: only if
you are not exclusively using a nomadic mail tool.
The sendmail utility is the back end to most of the mail user interface programs
such as mailtool and mailx and is responsible for sending mail to remote hosts
using the Simple Mail Transport Protocol (SMTP).
The sendmail utility is not affected when the network is disconnected. Most local
mail processing can still be accomplished. The front end mail user interface
programs will still operate and can still read, delete, copy and move mail messages
in the system’s inbox (/var/mail/username) as well as in any local mail folders.
You cannot, of course, send mail or receive it from remote systems.
With minor changes to a few files, outgoing mail can be composed and sent from a
user interface program, and sendmail will queue the mail until the network
connection is established or until a queue timeout period (the default is three days)
is exceeded, but only if the full address of the recipient can be determined (either
because the original mail contains the full address or because it contains a mail alias
that can be expanded to the full address).
Remote Mail Host
A remote mail host is another host through which sendmail routes all outgoing
mail. When your system is connected to the network, mail will take an extra hop to
the mail host before it is delivered. When your system is disconnected, a remote mail
host provides automatic queueing of new mail messages until the network is
reconnected. This means you can still compose and “send” mail messages when
disconnected. The messages will be delivered to the remote mail host shortly after
reconnection.
