My ISP assigns my IP address dynamically. For this and other reasons I have to relay all my outgoing email through my ISP's SMTP email relay. I tried to enable sendmail SMTP client-side authentication on my FreeBSD 4.9 system by adding this line to my sendmail.mc file: FEATURE(`authinfo', `text -o -k0 -v1 /etc/mail/authinfo') and creating the file /etc/mail/authinfo with these contents: AuthInfo:mail.covad.net "U:userid" "P:password" (of course "userid" and "password" are not the real values). When my sendmail connects to the email relay, the email relay says (in SMTP speak): 250-covad.net 250-AUTH LOGIN PLAIN 250-AUTH=LOGIN PLAIN but there is no obvious exchange of authentication information and my ISP's email relay sometimes rejects my attempts to submit email for relay. This is a typical SMTP rejection message: 553 sorry, that domain isn't allowed to be relayed thru this MTA (#5.7.1) Sometimes my email gets through. I don't know why. When I send email via Netscape, Netscape does authenticate itself to the email relay. Note: I did do a "make sendmail.cf" in /etc/mail after changing the .mc file and I did restart the sendmail daemons before sending the rejected email. The authinfo file belongs to root:wheel and has mode 640. I also tried it with mode 644 just in case. I also tried creating the file /etc/mail/access with the same contents and doing "makemap hash /etc/mail/access". The sendmail.mc file contains the standard line: FEATURE(access_db, `hash -o -T<TMPF> /etc/mail/access') Can someone who knows how this is supposed to work help me out? Is there an SMTP authentication protocol that protects the authentication information from network snoopers? Dan Strick strick@covad.net
