By default, a channel does not produce diagnostics output for its master and slave programs. You can reconfigure the channel so that it produces diagnostics output for either its master program, its slave program, or both.
When enabled, diagnostic output is written to the log file associated with the channel program. For more information on the channel's master and slave programs, refer to "Channels" on page 9. For more information on diagnosis using log files refer to the SIMS Reference Manual.

| 1. | In the Sections list of the Channel property book (see "To Access Channels Property Book" on page 121), click Diagnostics Output. |
| 2. | Determine whether diagnostic output is generated. |
|
To generate diagnostic output for the channels master program, click the first check box. |

|
To generate diagnostic output for the channel's slave program, click the second check box. |
|
|
To enable diagnostic output for both master and slave programs, click the check boxes associated with each of these choices. |
| 3. | Click the Apply button. |
| You are prompted to restart the IMTA. Click Yes. The debug output file is at /var/opt/SUNWmail/imta/log/ |
| The format of the channel debug file name is as follows: |
| channel_master.log_xxxxxx - master debug file (xxxxx is a random string). channel_slave.log_xxxxxx - slave debug file (xxxxx is a random string). |

Performance Tuning |
By default, the SMTP channel allows an unlimited number of recipients on a message without deferring processing. Too many recipient addresses can result in a delay of message processing. If the delay is long enough, network timeouts can occur and this in turn can lead to repeated message submission attempts and other problems. You can specify a limit of recipients for a single message at which message processing is deferred. When the specified number is exceeded, the message is enqueued and the remaining recipients are not verified on-line. Non-delivery receipts are generated for recipients later found undeliverable.
