Error 0002 when sending SMTP emails

 

Problem:

Solution:

• Use the iSeries PING command to make sure the TCP/IP address or host name can be PINGed. 
• If the TCP/IP address continues to fail, create a Host Table entry for the system and use that instead of the TCP/IP address:
  1. On a command line, type GO CFGTCP.
  2. Choose 10. Work with TCP/IP host table entries and make the changes you need.
• If using the Host Name still doesn't work, use the iSeries TELNET command with Port 25 to see if you can connect to the outbound SMTP server.
• If TELNET doesn't work, you most likely have an SMTP mail server connectivity problem.
