Welcome. And sorry about the late response.

You are using several values in the format string. Does it make a 
difference which one you would expect to provide a value? I mean, can 
you reduce the problem to involve `list-id.identifier` and/or one of the 
other values?

Hmm, are you sure you are not using this somewhere else? Try this:

	grep "list-id.body" ~/Library/Application\ 
Support/MailMate/Mailboxes.plist
	grep "list-id.body" ~/Library/Application\ Support/MailMate/Resources/

Or maybe this:

	defaults read com.freron.MailMate | grep 'list-id.body'

Based on your description I suspect there is a MailMate bug. I suggest 
you try to reduce the problem to a single column and header value. Then 
we can debug off list. (Ideally, I'll be able to reproduce the issue.)
