I had to stop using greylisting as mail when bounced just never got
resend to us, not sure if it to do with how the dns is setup 

cartoonsaloon.ie.       79      IN      MX      10 copper.host.ie.
cartoonsaloon.ie.       79      IN      MX      20 iron.host.ie.
cartoonsaloon.ie.       79      IN      MX      5 mail.cartoonsaloon.ie.

;; AUTHORITY SECTION:
cartoonsaloon.ie.       164320  IN      NS      quark.host.ie.
cartoonsaloon.ie.       164320  IN      NS      knox.host.ie.

;; ADDITIONAL SECTION:
mail.cartoonsaloon.ie.  79      IN      A       193.120.103.218
copper.host.ie.         11684   IN      A       212.147.138.29
iron.host.ie.           6670    IN      A       212.147.138.26
knox.host.ie.           10216   IN      A       212.147.138.130
quark.host.ie.          8807    IN      A       212.147.138.132

Host.ie used to have a catch all email setup i turned off ages ago 
As I am not using copper.host.ie or iron.host.ie should i get host.ie to
delete these entries from the DNS as from what i gather if
mail.cartoonsaloon.ie greylists the the email the senders smtp server
will try to resend it to copper.host.ie and then to iron.host.ie  but as
the email addresses don't exist they get bounced is my assumption
correct ?
