>This (multiple A records) works for me, at least approximately. Both >Bind and MS DNS will round robin when multiple A records exist for the >same hostname. What is your setup? FreeBSD 6.2 with Sendmail (initially) and now postfix. MS DNS with round robin (and TTL set to 0 on the records). Resolving with nslookup gives something like: smarthost.domain.tld 192.168.0.1, 192.168.0.2, 192.168.0.3 If I kill 192.168.0.1 then it goes on the second one. But this is failover, and I need (approximately) load balancing. I understand this is related to the MTA and not to the OS, but hopefully someone solved this problem using Sendmail or Postifx that are both used on FreeBSD. Thanks
