Think of Postfix/Sendmail/Exim like the post office...they'll take your mail, and put mail in your box, but it's up to you to get it. http://my.lostinfo.com/files_other/cyrus_imap/ Was my original walkthrough. It's a bit dated now but it might give you a good overview of what we have in place and running now. http://my.lostinfo.com/files_other/courier-imap/ Was my earlier attempt using courier-imap, however I was unsuccessful in getting the information I needed as to how to get a "black-box" setup working. It's got a kind of overview of courier as well tho'. Here's a little flowchart for you... It's generic but you'll get the idea of how mail flows through the system: MAIL -> Sendmail / Exim / Postfix Accepts the incoming mail via SMTP, sends it on to ---> Cyrus / Courier-IMAP or perhaps it just puts it in the /var/mail files like sendmail does Outlook / Netscape Mail / Web-based client / Hundreds of *nix clients Allows you to check the mail, via POP3 or IMAP --> YOU John Straiton jks@clickcom.com Clickcom, Inc 704-365-9970x101 > -----Original Message----- > From: Keith Spencer [mailto:keith@smmc.qld.edu.au] > Sent: Thursday, December 12, 2002 6:54 PM > To: jsmailing@clickcom.com > Cc: freebsd-questions@FreeBSD.ORG > Subject: RE: are virtual mail account users possible with > sendmail on freebsd > > > Hi and thanks John, > Yes I know how to setup mysql...Is imap or postfix (whatever > does the job...imap I guess if I dont bother about smtp auth) > easy to get to auth with mysql? what do I need where do I > look perhaps a tute?
