As we migrate from sendmail / procmail to zimbra I have a question about zmmsgtrace or other method of delivery audits.

In the past I could address the "He/she said they did not get the message" with a procmail log

grep -A2 /var/log/procmail.log

The subject is so useful when dealing with lost or missing messages. Is there a method to get this sort of detail?
