> bind-9.2.1-16 > sendmail-8.12.8-9.90 Please let me know if you find out more about this. ;-) One issue I know about: bind from RHL9 had some threading issues. I don't know how much impact they could have, but maybe updating that to a newer version could resolve things. Another item could be running nscd. You said you run a local named. Does /etc/resolv.conf always point to it? sendmail only reads /etc/resolv.conf on startup... greetings, Florian La Roche -- Shrike-list mailing list Shrike-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/shrike-list
