I have a friend who wants to set up an e-mail server. We wants to be able to accept e-mail from outlook, etc. via SMTP from his customers. In otherwords, he needs to support relaying from other machines on the internet... Of course we don't want to set up an open relay. But we also don't know the ip addresses of the customers either, so we can't use the sendmail access table to accept mail from certain machines. Outlook, etc appears to support authentication on mail connections. Anyone know how to set this up with sendmail? Is this what sasl is used for? _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
