Adding Mail with Exim - Verify the DNS MX Records

(Page 7 of 9 )

Mail servers make heavy use of DNS resolution. The Mail exchanger (commonly referred to as MX) field in the DNS records should be updated and verified so that incoming mail can be directed to the new mail server.

A discussion on DNS records is beyond the scope of this tutorial. However, a sample record is shown as an example.

$TTL 86400  ; Default TTL example.com.   IN  SOA  ns0.example.com. admin.example.org. (       2005031401  ; serial       10800       ; Refresh period       3600        ; Retry interval       604800      ; Expire time       10800       ; Negative caching TTL ) $ORIGIN example.com.  IN  NS    ns0.example.com.                       IN  NS    ns1.example.com.                       IN  MX 1  example.com.                       IN  A     10.4.160.3 www                   IN  CNAME example.com. mail                  IN  CNAME example.com.
