[Ayatana] Can't send email to Ayatana list

[Richard Gaskin <ambassasdor@xxxxxxxxxxxxxxx>]

I'm subscribed to the Ayatana list and receive all messages daily, but
I'm apparently unable to send to the list.

I've verified that the email address used for my subscription matches
that in both the "from" and "reply-to" fields of my email client
("ambassador@xxxxxxxxxxxxxxx"), but still I can't send messages to the
list.

No bounce notice is received, and I've white-listed all launchpad.net,
ubuntu.com, and canonical.com addresses in my mail server so I would
expect any such communications to get through.

Can you please help me figure out what I need to do to be able to
participate in the Ayatana list?

Thanks for your help -
