Hi Bjorn and Mikkel,

Thanks to both of you, I have tracked this down to a cron job, which
was sending status e-mails to 'root localhost com' rather than
'root localhost'.

I am still trying to figure out how/when the behavior changed, but it
may very well have been some oversight on my part. I don't recall this
situation with Postfix before a few weeks ago, so something within that
recent time frame changed and I will review offline rsnapshot backups of
configuration files to see what I can see.

This also helps to explain why there were SMTP related errors in the
maillog, which was confusing me further, given that I was not expecting
any mail to be sent outside of my local system.

Thanks again to both of you for your assistance!
