The MX for host2.domain.topdom is mailhost.domain.topdom; the latter is unreachable by host1, hence the permanent failure. > mailhost.domain.topdom does not exist in DNS, but host1 can send > mail to other mailservers all over the world. The fact that host1 can send mail anywhere else is irrelevant; fix the MX entry or make mailhost.domain.topdom real/reachable from host1. Or remove or adjust the MX entry for host2.domain.topdom so host1 sends mail to host2.domain.topdom instead of its mailhost.domain.topdom. -- Sahil Tandon <sa...@tandon.net> _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
