Hi all,
I have a linode that I just use as a webserver and have installed logwatch on it. The server has been running for a couple months now and I send the daily logwatch report to my other linode vps that runs my iredmail installation. In the last few days ive noticed that I have not been receiving the logwatch report and the mail log reports the following:

The logwatch report has been received perfectly fine since inception until the last few days where it is now being reported as blocked by zen.spamhaus. If I check my server ip, my ipv6 ip and my domain on the spamhaus site, neither are listed as blocked.
How can I stop my iredmail server from blocking this email? It is the only email that ever gets sent from the webserver currently.
