Ok ,
 
I upgraded to 2.6.5 - and still fails,
 
eg
 
Nov 17 10:42:21 obeml1 postfix/smtp[5444]: [ID 197553 mail.info] 6D12F239406: 
to=<postmas...@eurocommerce.ie>, relay=none, delay=40, delays=0.26/0/40/0, 
dsn=4.4.3, status=deferred (Host or domain name not found. Name service error 
for name=eurocommerce.ie type=MX: Host not found, try again)

 
however when i DIG i get 
 
 ; <<>> DiG 9.3.2 <<>> @localhost eurocommerce.ie MX ; (2 servers found) ;; 
global options:  printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status:

Should this new postfix not just ignore the bad entryt and use the primary mx 
anyway ?
 
or is postfix ignoreing all due to the error

Postfix versions 2.3 and later skip a DNS record with a bad name.

Unsupported Postfix versions pretend that the lookup failed when
the result is invalid.
