Are you maybe using relay_by_mx? If so then you have a canonical DNS problem. The way sendmail works out how to relay by MX is it looks at all the ips on all it's interfaces. In your case this would be 202.128.97.2 it then does a reverse lookup which gives ns1.isa.net.au So if it sees ns1.isa.net.au in an mx record it will relay. so you probably need to change 202.128.97.2 to point to mx2.isa.net.au or use ns1.isa.net.au as your MX record. -- John http://www.inodes.org/ -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
