I hope I am posting to the correct list. I have been trying to set up SMTP and POP3 on a FC3 installation. I have pop3 working fine and can download my email using outlook or thunderbird. Sending email is a different story. I have read about 50 web pages about setting up smtp authentication and they all say (generally) the same thing, but don't help me out. I am getting relaying denied errors when I try to send any email from Outlook or Thunderbird. I CAN send mail to <my_username>@<hostname_of_box>.com ... but if i send to an outside domain I get the error. The AUTH section of my sendmail.mc file: define(`confAUTH_OPTIONS', `A p')dnl TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl When I get a mail failure i get this from /var/log/maillog: Feb 4 11:59:34 localhost pop3-login: Login: rcurts [::ffff:4.8.55.148] Feb 4 11:59:36 localhost sendmail[7892]: j14GxW9N007892: from=<rcurts@xxxxxxxxxxxxxxxx>, size=0, class=0, nrcpts=0, proto=ESMTP, daemon=MTA, relay=[4.8.55.148] I put up my sendmail.mc at http://www.intrastudios.com/docs/sendmail.mc.txt in case someone had a thought of something that might be wrong in that file. I hope someone has a suggestion. :) Cheers, Robin Curts
