I have received the message below from the listowner of a particular list. The problem outlined seems very unlikely to me, and I have not experienced it as a member of that list. Can anyone shed light on why that list has a problem with other addresses in the To:, CC:, and bcc: fields?

Plaud <[log in to unmask]> Reply-To: BEHAV-AN <[log in to unmask]> Subject: When posting to Behav-An via Email, Please Read As probably many of you know, when you post to Behav-An via email, it is imperative that the To: line in your posting be addressed to Behav-An ([log in to unmask]). If you CROSS-POST (i.e., send a message to some other list or some other person and include Behav-An in the cc: or bcc: fields, or in the to: field after some other email address), your message will be bounced back as undeliverable. As I am still receiving these error messages, and it takes time and effort to figure out why the message was bounced, I am hoping that this little tutorial will solve this problem. Thanks.
