Suddenly, yesterday, I began receiving dozens of rejection notices such as the following: >The enclosed message, found in the BLUES-L mailbox and shown under the spool ID >7686 in the system log, has been identified as a possible delivery error notice >for the following reason: "Sender:", "From:" or "Reply-To:" field pointing to >the list has been found in mail body. > I did some testing, and I think that all replies to the list are leading to this error message. Our list parameter "reply-to" is "sender, respect"; the parameter "sender" is the default "list". These parameters haven't changed. The "sender" field on these rejected messages is the list address. Why am I suddenly receiving these error messages? David Silberberg Blues-l Co-list-mom [log in to unmask]
