You've not been paying attention. ;) This isn't new. On two machines (that are internal and only allow mail via localhost) that do not have the most recent updates applied, and use the default config: $ rpm -q sendmail sendmail-8.11.6-3 $ cat /etc/redhat-release Red Hat Linux release 7.2 (Enigma) $ grep -B 3 accept_unresolvable_domains /etc/mail/sendmail.mc dnl We strongly recommend to comment this one out if you want to protect dnl yourself from spam. However, the laptop and users on computers that do dnl not have 24x7 DNS do need this. FEATURE(`accept_unresolvable_domains')dnl $ rpm -q sendmail sendmail-8.11.6-15 $ cat /etc/redhat-release Red Hat Linux release 7.3 (Valhalla) $ grep accept_unresolvable_domains /etc/mail/sendmail.mc FEATURE(`accept_unresolvable_domains')dnl - -- - -Michael pgp key: http://www.tuxfan.homeip.net:8080/gpgkey.txt Red Hat Linux 7.{2,3}|8.0 in 8M of RAM: http://www.rule-project.org/ - -- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE+ZWJZn/07WoAb/SsRApRmAJ48IyPrymz4H0cMIw/UuHst+JjwqgCdGndU bVPktRpbXgsImQIBe3Jwt5w= =BzKC -----END PGP SIGNATURE----- -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
