Error 00006 when sending SMTP emails

 

The TCP/IP address and host entry on the AS/400 is correct, but when you ping the SMTP mail server, it takes about 25 seconds to receive a response.

 

This is a network response-time issue on the user's AS/400 system.

 

To make sure the AS/400 looks at the local Host Table entries before checking the DNS to resolve a host name, run the following command:
