Question Mail and remote logins & resolv.conf

I have a little problem and is causing me a head ache and hope that someone can help me with it.

Ok, heres the setup.

1. I have a unix server that users connect to from remote sites via telnet & ftp.

2. On the machine a backup runs every night which emails root with information on the backup. The root account has a .forward file which forwards the email onto a list of other users using Outlook and not their unix mail account.

Heres the problem. A while ago all the DNS for our site was change and since then the backup mail and remote logins will not work together properly. The DNS on the unix machine was changed to match all the new DNS addresses but the only way to make connection time near the required speed is to delete the resolv.conf file, which then stops mail working.

Its a DNS problem but does anyone have any idea about now to make the connection time better and still use the resolve.conf file.

Thanks for your time.

When someone connects to your server with telnet or ftp, the server will try to resolve the IP address they are connecting from. The connection will usually hang while the lookup is performed. Make sure that your DNS servers can properly resolve those IP's and your connection time should speed up.

Basically ftp & mail uses DNS. So make sure that your DNS Server works fine. Or you can add the name of your machine to /etc/hosts, so the DNS will find your machine faster using /etc/hosts.
