I don't know much about AD, but my impression is that it likes to be the boss of everything (typical for MS). So I think the answer to Max's question is: yes, and no. ;) Bind has the capability of having multiple views, which can be set up for internal and external views. So if a computer inquires internally (from the lan), then the local address is given, and if an external computer inquires (from the internet), the public address is given. This is essentially what AD's name resolution needs to do to solve this. I don't know if this can be done with AD, nor how to make AD do it. If AD can't do it, I would use a different name for the internal address. That way you'll still have internal access with the internet is down. OK will try to configure local dns in AD and then re-check. >> 2) They got 1 ERP software in network which sends mail to their >> client.

The port doesn't really matter. What's the domain name that the ERP software is using? Can you configure it in the ERP software? There ERP software needs only few things like incoming server, outgoing server, sender id and receiver id. Now here sender id and receiver id are from local domain of QMT. But getting error "421 Refused. Your reverse DNS entry does not resolve" in their ERP software. >> 3) I want to disable RDNS check for local ips. How to do this and any >> harm in doing this? Do you use spamdyke? If not, install it. That will solve this problem. Alternatively, you can configure local clients to use port 587. Yes, I'm using Spamdyke. There is no option for port else I planning to change smtp port to 587. >> 4) How to disable MX check on my QMT. Why? Is this related to #1? Disabling MX check is not a very good idea, as bounces would have nowhere to go. Yes it is related to #1. Anyway will try will local DNS. -- -Eric 'shubes' --------------------------------------------------------------------------------- Qmailtoaster is sponsored by Vickers Consulting Group (www.vickersconsulting.com) Vickers Consulting Group offers Qmailtoaster support and installations.
