[Clo-devel] Trac ticket notifications

[Raymond Toy]

This used to work and I don't know when it stopped working, but
whenever I create (or modify?) a ticket, I get an message displayed
with the ticket:

Warning: The ticket has been created, but an error occurred while
sending notifications: {u'toy.raymond at gmail.com': (550, 'Verification
failed for <cmucl-devel at common-lisp.net>\nUnknown user\nSender verify
failed'), u'cmucl-ticket at common-lisp.net': (550, 'Sender verify
failed')} 

Not quite sure what this is trying to tell me,  

Actually until very recently, as an admin, I used to receive messages
to allow messages to be sent to cmucl-ticket at common-lisp.net, even for
my own tickets. A bit annoying, but it worked.  Now I get nothing.

Hints or help would be greatly appreciated.
