My conclusion: Canonical is blacklisted by http://www.uceprotect.net.

For now, I commented out these lines from the smtpd_recipient_restrictions
section of /etc/postfix/main.cf:

    reject_rbl_client dnsbl-1.uceprotect.net,
    reject_rbl_client dnsbl-2.uceprotect.net,
    reject_rbl_client dnsbl-3.uceprotect.net,

+ I did a postfix reload.

I hope that this mail will arrive AND I hope that this won't increase the
amount of spam hitting my inbox.

Should I file a bug somewhere in Launchpad? Because this problem is not
software related. I don't know what the proper procedure is.
