Configuring the SMTP connection pool properties
Ensure that the Transaction server SMTP connection pool properties match the SMTP server timeout to avoid periodic mail failure. These failures can occur due to mail being sent with a connection that is expired on the SMTP server.
The Transaction server SMTP connection pool properties can be modified to avoid mail
failures. You must either:
- Set Unused Timeout to below the SMTP server connection timeout; and
- Min Connections to 0.
- Set Aged Timeout to below the SMTP server connection timeout.
For more information about these parameters, see the WebSphere Application Server documentation.
