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.

NAME

       saslfinger - A utility to collect SMTP AUTH relevant configuration for Postfix

SYNOPSIS

       saslfinger [-chs]

DESCRIPTION

       saslfinger  is  a utility to collect SMTP AUTH relevant configuration for Postfix. Depending on how you run it, it will search for informa-
       tion on server-side or client-side SMTP AUTH configuration settings in Postfix and Cyrus SASL.

OPTIONS

       -c     If you run saslfinger with the option -c it will collect data required for client-side SMTP AUTH.  Client-side  SMTP  AUTH  is  when
	      Postfix smtp daemon uses SMTP AUTH to authenticate itself with a remote mail server that offers SMTP AUTH.

	      saslfinger will try to telnet to all hosts listed in smtp_sasl_password_maps, if it may read smtp_sasl_password_maps

	      The  telnet  test  verifies  your host is able to reach the remote servers and shows what AUTH mechanisms they offer - in some cases
	      this is required to debug client-side SMTP AUTH.

	      Important: By default smtp_sasl_password_maps must be read-only to root, since these maps contain the  usernames	and  passwords	to
	      authenticate.  If  you  run  saslfinger  as  root access will be no problem, but saslfinger will fail if you lack the permissions to
	      access smtp_sasl_password_maps.

	      If you want to run the telnet test, but don't want to run saslfinger as root change permissions of smtp_sasl_password_maps  so  that
	      the user running saslfinger may access smtp_sasl_password_maps while you debug.

	      *note: You don't need to worry about saslfinger doing anything with the username or password stored next to the remote hosts in your
	      smtp_sasl_password_maps; saslfinger completely ignores these informations!

       -h     If you run saslfinger with the option -h it will print a little help message that tells you about the options you can use.

       -s     If you run saslfinger with the option -s it will collect data required for server-side SMTP AUTH.  Server-side  SMTP  AUTH  is  when
	      Postfix smtpd daemon offers SMTP AUTH to mail clients.
