<ignore_mx_lookup_error_text>
This parameter controls what happens when a name server fails to respond to an MX lookup request.[br]
By default,Postfix defers delivery and tries again after some delay.[br]
Set enable to force an A record lookup.[br]
This refers to the fact that some DNS servers return SERVFAIL instead of "does not exist" when asked for a MX record.[br]
When disabled,  Postfix NEVER tries the A record,[br]
When enabled it looks for the A record</ignore_mx_lookup_error_text>

<disable_dns_lookups>Disables Postfix DNS client</disable_dns_lookups>
<disable_dns_lookups_text>
To force postfix to read /etc/hosts file for example, enable this option.[br]
In that case, you can't use MX record and you may want to specify relayhost to send outgoing mails.[br]
Note: Enable this  option just disables Postfix DNS client and makes Postfix use [b]libc resolver[/b], does not disable any DNS lookups of both Postfix and operating system.
