Recently my Logwatch reports are getting stuck in smtpd with timeout errors. I turned up the logging level and this is what I see:

Any other mail gets through just fine (e.g. sendmail me@comcast.net). I have to wonder about the construct of the message generated by Logwatch. Any troubleshooting suggestions would be appreciated!

(Interestingly, rebooting the server usually makes the first message from logwatch go through without a problem, but subsequent days get "stuck")

Thank you!
