Hi there, Recently, updates from MoinMoin have started getting quarantined due to sender verification failing. On investigating the problem, it seems that an assumption about the webmaster mailbox is incorrect: 220 bag.python.org ESMTP Postfix (Debian/GNU) MAIL FROM: <> 503 Error: send HELO/EHLO first HELO argon.maildefence.co.uk 250 bag.python.org MAIL FROM: <> 250 Ok RCPT TO: webmaster@python.org 553 invalid bounce (address does not send mail) The MoinMoin instance on Python.org is sending mail as "webmaster@python.org". Can somebody take a look? Or at least tell me who to contact. Thanks, David. PS: Please CC me in replies as I am not currently subscribed. -- It's never too late to have a happy childhood.
