/var/mail in this system is a locally attached storage array running
UFS. Over the weekend, I set soft_bounce=yes, and mail has
successfully been delivered. Here's a sample:

This morning, I've taken the advice of switching to the dovecot LDA
"deliver" and that seems to be working. I'll be keeping an eye on it.

Thanks for the advice.
