I ran into a similair problem when our local university started blocking based on "the DUL list" (http://mail-abuse.org/dul - site currently down?). To get my wife's email to forward to their account, or to send to any friend of mine at the university, I had to do two things: 1 - Figure out what my ISP's upstream mail server was and how I could get it to relay messages for me 2 - Make Qmail do this for me. 1 was easy - I called them and they said "use smtp.sasktel.net and authenticate with any of your account username/password combinations" 2 was more difficult. I downloaded an SMTP-patch for Qmail from http://madhaus.utcs.utoronto.ca/qmail/qmail-remote_authenticated_smtp.patch (documentation at http://www.soffian.org/downloads/qmail/qmail-remote-auth-patch-doc.txt) and re-build qmail. Then I added the following to my /var/qmail/control/smtproutes: .jimramsay.com: :smtp.sasktel.net base64encodedusername base64encodedpassword This means: Anything going to *.jimramsay.com just lookup the MX record as usual. Everything else route via smtp.sasktel.net, logging in with the given username and password, and it all works wonderfully now! If your ISP's upstream server does not need authentication and relays simply because you're in its subnet, you wouldn't need the patch, and your smtproutes entry can skip the username and password portions, of course! Good luck! Jim _____________________________________________ tmda-users mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-users
