[Mailman-Users] Can't Subscribe To My List

[Rejean Proulx]

I just installed mailman and set up a mailing list.  When I try to send a
subscribe message locally, here is what I get.  What have I forgotten to do?

The message could not be sent because one of the recipients was rejected by
the server. The rejected e-mail address was
'blindetext-request at interfree.ca'. Subject '', Account: 'rejean', Server:
'interfree.ca', Protocol: SMTP, Server Response: '451 Cannot check
<blindetext-request at interfree.ca> at this time - please try later', Port:
25, Secure(SSL): No, Server Error: 451, Error Number: 0x800CCC79
