Hi all; I have a FreeBSD 3.2 machine that wears many hats... Among other things, this machine does web, file, and mail hosting for outside clients (i.e., clients on other networks). Sendmail is giving me some problems, though. I've searched the mailing list archives (and my own fairly extensive archives)... And sendmail.org... But I never did find a good way to do what I'm looking for. Basically, this machine is a mail host. My clients receive, or can purchase, email accounts, something like name@sasknow.com. I also do virtual hosting, so they may have their name@theirdomain.com. However, I am having the old problem with relaying :-) I have created an /etc/mail/relay-domains file with entries for the other machines on the local subnet. (Actually, I just added the line "10." to allow the entire subnet). I understand that, to curb spam abuse, relaying should NOT be configured "wide open"... However, how else can I ensure that clients with SMPT access not be denied relaying when sending messages out? If it IS indeed necessary to configure sendmail wide open (promiscuous feature), what would be the best way to implement this so that I can still block troublesome domains? I looked at the documentation for /etc/mail/access, but it seemed a bit sketchy.... And I'm not even sure if it's possible to configure sendmail to accept from all and deny from some using the access method.
