problems with mentors.debian.net mailserver

["Michael Gilbert" <michael.s.gilbert@gmail.com>]

hello,

i tried to sign up for a mentors account today
(http://mentors.debian.net/cgi-bin/maintainer-signup), but got the
following error,  which appears to be a mailserver failure:

 Traceback (most recent call last): File
 "/home/www/mentors.debian.net/cgi-bin/maintainer-signup", line 99,
in ? addError =
 signup.addNewMaintainerToDatabase() File
 "/home/www/mentors.debian.net/cgi-bin/Mentors/Signup.py", line 114, in
 addNewMaintainerToDatabase
self.mail_new_hash(self.formfields.getvalue('email')) File
 "/home/www/mentors.debian.net/cgi-bin/Mentors/Web.py", line 515, in
mail_new_hash

 line 695, in sendmail raise SMTPRecipientsRefused(senderrs)
 smtplib.SMTPRecipientsRefused: {'': (554, '5.7.1 : Relay access denied')}

i then tried to send a mail about this to support@mentors.debian.net,
but it bounced:
