Error 20005

Error message ...

"An error occurred while processing the message “splatmatters
slat splats flatter!”.

A stored mailbox reference refers to a mailbox which no longer
exists, probably because it was previously deleted. (Application
error code 20005).
=====

This mailbox does exist, and the transfer is set up using the
form in this Mailbox's Info.
The set-up is:
If | From | Contains | matters
The from address is: samcl...@splatmatters.org

I tried changing all the settings to something else, saving,
changing them all back, saving. Which seems to clean up
corruption in data entries like these, sometimes. Lots of other
mailboxes set up this same way are working. Data entered by
copy/ paste to avoid spelling issues. I'm stumped!

Any wisdom anyone can pass along will be greatly appreciated.
