I noticed lots of these in a customers Control error logs:

[12/Dec/2012 10:56:26] Unable to get address where to send failure notification, message: ./mqueue/81e84d4f-4557-064b-9f1d-f13e929e04e7.eml, retryNo: 0
[12/Dec/2012 10:57:26] Unable to get address where to send failure notification, message: ./mqueue/9a65b7ef-7c22-6c43-80bd-30e7a3560057.eml, retryNo: 0

I sshed in, but there was nothing in mqueue.

Poking around a bit I found these in ~/winroute/tmp

failure-101768.tmp failure-144991.tmp failure-25865.tmp failure-53843.tmp
failure-104296.tmp failure-144992.tmp failure-25923.tmp failure-54136.tmp

I started laughing when I actually looked at a few:


Subject: Kerio Control delivery failure notification
Content-Type: text/plain;
Content-Disposition: inline

Kerio Control was unable to deliver message. Remote server's reply:
450 4.7.1 Please try again later
Message headers follow:

That's graylisting from Kerio Connect Smile I assume this was stuff Control stripped viruses from and then tried to deliver itself?

Once I stopped chuckling, I realized that I do have a question: is Control going to clean up this junk eventually or do I have to clean them out manually? Probably I should set Connect not to greylist Control?

You should exempt your Control Box as well as all local traffic from the Greylisting, Spam Assassin, and all of the other spam filters as well as whitelist them to insure proper delivery of messages like this... if you are getting spam from your own network you have bigger issues.
