[Mailman-Users] Implicit destination

[Steve Burling]

One of our lists has someone post to it whose mail is held, with the error:

Blind carbon copies or other implicit destinations are not allowed. Try
reposting your message by explicitly including the list address in the
To: or Cc: fields.

But as near as I can tell, she *is* putting the list address in the To: 
field, it's just been munged (presumably by Micro$oft LookOut) to have 
quotes in funny places.  Here's what the To: field looks like from the 
listname.mbox file (edited to protect the innocent):

To: "list at icpsr.umich.edu" <'list at icpsr.umich.edu'>

Are those unnecessary single quotes inside the "<...>" confusing Mailman? 
Or am I missing something really obvious?
