25.3.4.8 MTA Logging – Incoming SMTP Message Routed Through the Conversion Channel

This example illustrates the case of a message routed through the conversion channel. The site is assumed to have a CONVERSIONS mapping table such as:

CONVERSIONS
   IN-CHAN=tcp_local;OUT-CHAN=ims-ms;CONVERT Yes

This example assumes option settings of LOG_FILENAME=1 and LOG_MESSAGE_ID=1.

1. The message from external user amy@siroe.edu comes in addressed to the ims-ms channel recipient bert@sesta.com. The CONVERSIONS mapping entry, however, causes the message to be initially enqueued to the conversion channel (rather than directly to the ims-ms channel).

2. The conversion channel runs and enqueues the message to the ims-ms channel.

3. Then the conversion channel can dequeue the message (delete the old message file).

4. And finally the ims-ms channel dequeues (delivers) the message.
