Re: POP3 accounts
You might also want to check out: http://www.qmail.org/ and vpopmail Debian package. The basic idea is that you don't use real usernames that exist on the server, but instead create "fake" ones (such as a user called [EMAIL PROTECTED]) just for checking pop3 email. Do some reading... also check out http://www.lifewithqmail.org/ which describes how to do it with Qmail (and no doubt other mail software have their own guides). - Original Message - From: "Robert Cates" <[EMAIL PROTECTED]> To: Sent: Wednesday, 11 February, 2004 7:02 PM Subject: POP3 accounts Hi, I would like to get a job at a nearby ISP, and therefore I'm trying to learn more on various (technical) aspects of the business.

Well, the way I have done it is by not using system accounts for email at all. All mail is owned by the "mail" user on the system, and the various POP boxes are stored in a MySQL database. The SMTP server looks up mail accounts in the MySQL database, and stores email (in maildir format) to /var/spool/mail/virtual/domain.com/user/. The POP3 server also works against the MySQL database, and fetches the email from the correct mailbox. I use Exim as an SMTP server, and tpop3d as a POP3 server. Both support looking up account info in a MySQL database. There are many different ways to handle this, but it's always done by looking up mail accounts in a different backend than the system account database (for example flatfiles, LDAP, MySQL and so on). -- Erik Grinaker <[EMAIL PROTECTED]> http://erikg.wired-networks.net/ "We act as though comfort and luxury were the chief requirements of life, when all that we need to make us happy is something to be enthusiastic about." -- Albert Einstein
