host smtp-relay.gmail.com smtp-relay.gmail.com has address 64.233.176.28 smtp-relay.gmail.com has IPv6 address 2607:f8b0:4002:c02::1c service sendmail restart again - and same behavior going to relay 203.inbound-mx.org Jerry _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
