Hello again! I have been reading Postfix and Sendmail to see if I can set up UCE rules based on a user name and password. I currently run a windoze program that allow's the user to log in to the SMTP server before sending an email. I am not an ISP, but I do host email for some companies. People who use the mail server don't always have an alternate SMTP server to use. To avoid the nasty spam problem, I require each user to log in to send a message. I wish to migrate the email server to postfix or sendmail, but have unable to find any documentation to support this setup. Am I missing something really basic or is this not possible?
