But some SMTP client needs to be running to send outgoing messages about system status, and to handle outgoing mail from locally logged in users running a mail client like mutt, which does not have a built-in SMTP capability. The default sendmail config does this without allowing connections from remote machines (only listens for connections from 127.0.0.1). >The only machine that needs Sendmail installed and running is the >mailserver itself. The client machines pick up their mail via either pop3 >or imap. [snipped good info on IMAP] That only works if each user has a mail account on the mail server, a setup which I recommend. There is no need to setup an SMTP server on multiple machines. >actually, even though your network isn't yet connected to the internet >you can and should be running DNS for your intranet machines so mail can >be accessed and made available properly to the client machines. Agreed, although sendmail should work with properly maintained host files. Another reason to run DNS is to reduce lookup times for your client machines when you do get connected to the Internet. They will be able to resolve addresses using your local DNS instead of sending a query up the connection to your ISP. Tony -- Anthony E.
