Whether that is convinient for you or not is another |matter. Hm. Well, ok. I just dug into my sendmail config and set up relaying only for mail destined to freebsd.org, and it seems to be satisfied now. I'm not keen on relaying all my mail through my ISP's mail relay (single point of failure and easier snooping), so I used the sendmail mailertable feature I found to relay just when dealing with @freebsd.org destinations. For the archives (to others that fall over this support tripwire and don't want to wildcard relay all of your mail), here are a few relevent bits: > cat /etc/mail/mailertable # # List of domains (possibly wildcarded) and destination mailers # ## .my.domain xnet:%1.my.domain ## uuhost1.my.domain suucp:uuhost1 ## .bitnet smtp:relay.bit.net freebsd.org smtp:smtp-server.nc.rr.com ^^^^^^^^^^^^^^^^^^^^^ change to your relay! Don't forget to rebuild the map: # makemap hash /etc/mail/mailertable < /etc/mail/mailertable And if you adapt the default /usr/src/etc/sendmail/freebsd.mc, you'll already have: FEATURE(mailertable, `hash -o /etc/mail/mailertable')dnl in your .mc. If not, add it and rebuild: # cd /usr/src/contrib/sendmail/cf/cf # m4 ../m4/cf.m4 /path_to_my_mc_files/my.mc > /etc/mail/sendmail.cf Randall -- Randall Hopper aa8vb@nc.rr.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
