When I installed Courier on my server, I already knew the basics from previous experience with qmail, but it still took quite some digging in the docs to understand how Courier handles aliases, mail filters and it also was the first time I heard of port 587. What you're supposed to do is: - Set up a /public/ smtp server on port 25. This smtp server only accepts incoming emails (emails intended for a user on your server) and doesn't do authentication. It also never relays emails anywhere. - Set up a /private/ smtp server on port 587 (see RFC-2476). Courier calls this server smtp-msa (msa = mail submission agent, i.e. thunderbird, sylpheed, evolution). All users on this smtp server must be authenticated and are then allowed to submit emails to be relayed to users on other servers (i.e. gmail, hotmail) - Set up a POP3 and/or IMAP server for local users to read emails. It looks like you tried to use Courier's port 25 as your mail submission port. "Authentication required" is reported because Courier does not relay mail from unauthenticated users (otherwise it would be an open relay). By setting AUTH_REQUIRED for port 25, you required everyone (including gmail and hotmail) to authenticate themselves, thereby rendering your email server unable to accept incoming messages. I don't know if it helps, but I documented the steps I've taken to set up Courier on my server here: http://www.nuclex.org/blog/personal/83-installing-courier-on-gentoo -Markus- ------------------------------------------------------------------------------ _______________________________________________ courier-users mailing list [email protected] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
