MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" X-Mailer: Kiltdown 0.7 Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG hello! i would like to have a couple of people access my mail server for secure POP or IMAP access, but also want to prevent relaying on sendmail (so i have relaying turned off right now). Now, the problem is, these people are accessing the server from various machiens and various accounts, and it's well nigh impossible to put their ip addresses or hostnames in /etc/mail/relay-domains. So, the question is, what means can I use to allow them to send mail without opening myself up to relaying? - i've tried the popauth suggestion on sendmail.org with only limited success (it's a mild PITA, and seemed unreliable, actually) - i can force them to always redirect their local ports on their machines, but the hassle factor for them goes up quite a bit there, which is also undesirable ... - many common mailers today suggest that there is a way to "log in" to outgoing SMTP servers? is this a way to get around this problem? do any FreeBSD-happy mailers support such a thing? - might i best be served by ditching sendmail and trying something else? any suggestions would be greatly appreciated. thanks! marc.
