I set up a Mailing List in Plesk for a client. The list has about thirteen email addresses (various domains like @yahoo.com etc.) It seemed to work for her for a while but on the last mailing she got this message (below) in ten separate emails for ten separate email addresses. In other words, almost the full list of addresses had this bounce message.
This is a Mailman mailing list bounce action notice:
List: Teachers
Member:
somebody@gmail.com
Action: Subscription disabled.
Reason: Excessive or fatal bounces.
Any idea what might be causing this and if there is a remedy?
