Here is what mailman's people said:<br>
<br>
"This message was delivered from Mailman to Postfix and then delivered by Postfix to Cyrus, possibly because this was to a local user and Cyrus is acting as the LDA, or possibly for some other reason, but in any case, if the mail wasn't delivered to the user, this is a question for Cyrus."<br></p>
