Than'k a lot and excuse me if i'm not so clear:
my local dns server , that is postfix server to, is used to filter
navigation of client (by domain black list)
so my local dns is under pressure and often mail give me error
resolving dns while sending mail to external.
I need to limitate this postfix error.
An example;
Out: 220 mydomain ESMTP Ermes
In: EHLO ciccio
Out: 250-mydomain
Out: 250-PIPELINING
Out: 250-SIZE 18000000
Out: 250-VRFY
Out: 250-ETRN
Out: 250-AUTH LOGIN PLAIN
Out: 250-AUTH=LOGIN PLAIN
Out: 250-ENHANCEDSTATUSCODES
Out: 250-8BITMIME
Out: 250 DSN
In: AUTH LOGIN
Out: 334 VXNlcm5hbWU6
In: aW5mb0BicnVub3NybC5uZXQ=
Out: 334 UGFzc3dvcmQ6
In: YXM4ZWUyNDU=
Out: 235 2.7.0 Authentication successful
In: MAIL FROM:<i...@mydomain.net>
Out: 250 2.1.0 Ok
In: RCPT TO:<daniela.mair@externaldomain>
Out: 451 4.3.0<daniela.mair@externaldomain>: Temporary lookup failure
In: RSET
Out: 250 2.0.0 Ok
Please show the logs for exactly that error. Because the logs show
WHAT failed (DNS, or mysql lookups)
