Interesting, I would think that ListServ would get over it… after a number of retries…

This error code is for aborted connections. You may have a message in your queue that is being blocked by a spam filter at the recipient’s server that is ending the SMTP conversation abruptly, without the usual 5xx messages.

I started getting these in my SMTPS#1 about 10 days ago. The error is being recorded once every few seconds and is creating a large log… Would somebody please explain the source of this error…
