If this is outbound SMTP, you can use a separate transport for that MX host's destination domain (assuming a known, manageable list). For that transport (say "vsmtp") set: vsmtp unix ... smtp -o smtp_tls_loglevel=summary,untrusted,certmatch and use the transport table to associate this with the destination(s) in question. The named log levels are not a stable feature of the smtp_tls_loglevel public interface, but in the short run you can use them for debugging. -- Viktor.
