I ask because there are so many different POP3 servers (although by covering qpopper, cucipop and ipop3d, you'd probably cover at least 60% of them), and the functionality lies not in sendmail, but rather in an external program constantly evaluating pop connections and putting hosts in and removing hosts from a "allow relay" database. And of course, several Win32 clients are stupid and SEND first and then receive, and don't allow you to choose; resulting in your users whining; notably, M$-crap e-mail clients. Pegasus and Eudora work correctly, from what I remember. Does anyone know of any SMTP server or e-mail client that supports username+password pairs for SMTP relaying ? If that was the case, I'm sure it would be relatively easy to patch the authentication module to do lookups via Radius or LDAP. --- Khetan Gajjar (!kg1779) * khetan@iafrica.com ; khetan@os.org.za http://www.os.org.za/~khetan * Talk/Finger khetan@chain.freebsd.os.org.za FreeBSD enthusiast * http://www2.za.freebsd.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
