What you were saying about your ISP having bogus entries is quite = possibly at least part of the problem. Sendmail uses real DNS and ignores /etc/hosts (because it needs to look = up MX records, there are no MX records in /etc/hosts). If you *really* = want to cheat that, you can run BIND on localhost and put a zone for = your own domain answering on localhost, and put 127.0.0.1 in = /etc/resolv.conf. =20 What is the hostname of your system? Can you post your full freebsd.mc? Have you rebuilt your sendmail.cf recently? -Dan > On May 18, 2023, at 12:19 AM, vagabond <vagabond@blackfoot.net> wrote: >=20 >> What do you have in /etc/mail/local-host-names? > ns.dreamchaser.org > it did have > ns.dreamchaser.org > ns.discoveriesinwood.com >=20 >> Are you using the stock freebsd.mc or sendmail.mc or whatever came = with the system? >=20 > mc file was originally derived from freebsd.mc from 10.x adapted to = 11.3 to 12.3 to 12.4 over the course of upgrades. > It has: > define(`confCW_FILE', `-o /etc/mail/local-host-names') >=20 >> All variants of domains you accept mail for should be in = /etc/mail/local-host-names, and if you want to map separately for each = domain, you need to set up a virtusertable. >=20 > don't need to map separately. >=20 > Originally I accepted 2 domains, but to get it running I'm willing to = change that to only 1, > dreamchaser.org > I just got rid of the other entry in local-host-names and bounced = sendmail; > the error persists. > Any other places I could be messed up? >=20 > Thanks, >=20 > Gary
