Name
trace smtp — trace smtp transactions
Synopsis
trace smtp add [ binding_name ] [ domain_name ] [ file_name ]
trace smtp list
trace smtp remove [ tracer_id ]
Description
10:47:35 /tmp/2025> trace smtp add <binding|*> <domain|*> <filename> 10:47:35 /tmp/2025> trace smtp remove <tracer_id> 10:47:35 /tmp/2025> trace smtp list
The trace smtp command allows fine-grained SMTP transaction-level logging to a specified file. It can be enabled by binding and domain combination. If * is specified for binding or domain it will match all bindings or domains, respectively.
Note
The trace smtp command traces outbound SMTP connections only.
In order to debug SMTP transaction to problematic-domain.com, one would:
10:47:35 /tmp/2025> trace smtp add * problematic-domain.com /var/tmp/smtp.log Registered smtp tracer #1 10:47:35 /tmp/2025> trace smtp list [ 1] binding: * domain: problematic-domain.com file: /var/tmp/smtp.log @ 29
Once sufficient debugging information has been collected, the debugging can be disabled as follows:
10:47:35 /tmp/2025> trace smtp remove 1 Removed smtp tracer #1
To set the permissions of smtp trace files see trace_smtp_mode.
