Hi Noel, i not agree with you. First of all if the nameserver is not configured correctly etc we should not try to "take care" and give the admin a chance to correct it He should get sure what he do before change the config.. I think most admins and users want to get the error as soon as possible. Let me give you an example why the old behavoir is bad: Think about you have a costumer where you installed james. He sended an email with an importent text out and not notice that he has a misstyping in the domainname. The domain he used as recipient domain does not exists. But he not get the bounce back till the configured retry count was reached.. (about 5 days). Because of that he not notice that he had a misstyping in the domainname, so he lost a job which whould hat brought him 1 000 0000 Dollars. How you whould explain him this ? This is not acceptable for me.. If we have an other DNS error then a temporary connection problem we should bounce as soon as possible. Don't get me wrong.. im not aggressiv.. I only try to explain you why i think the old behavoir is really bad! bye Norman --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
