... apparently breaks various Imail functions in 7.1 or thereabouts. OHN MUST be mail.domain.com. ># DNS Records shows: > >domainA.com > MX mail.domainA.com > A 192.10.11.12 > >domainB.com > MX mail.domainA.com NOTE: the DNS MX hostname has NOTHING to do with the Imail OHN, so you can use the same MX hostname for all domains: AnyDomain.com. MX10 mx1.ISPdomain.com. >PTR lookup for 192.10.11.12 showed: name = domainA.com The best you can do is to have an ip's PTR hostname match that hostname's A record. In reverse zone: $origin rk.wo.net.in-addr.arpa. 34 PTR my.host.name. To match in forward zone: my.host.name.

There is only one effective PTR record for an ip, so with multiple virtual Imail mail domains behind one ip, you cannot match all the Imail mail domains. >And is it also acceptable to have a different domain name on the >Host Aliases just like the case above wherein [EMAIL PROTECTED] may >receive mails sent to [EMAIL PROTECTED]? yes Len www.menandmice.com/DNS-training : DNS Training BIND8NT.MEIway.com : ISC BIND for NT4 & W2K IMGate.MEIway.com : Build free, hi-perf, anti-abuse mail gateways Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
