In my experience this is not a Mailman issue, per se, but an Exchange issue on the sender’s or recipient's end:

When sending the mail using Mailman, The email body content is sent as an attachment (ATT00001.txt). We face this type of issues only in outlook. Could you please suggest us the solution for the same. What does your list do to this mail. I.e. have you set from_is_list or dmarc_moderation_action to Wrap Message? Actually, the most likely explanation is the list has set Non-digest options -> msg_header, and the incoming message (after content filtering) is other than a single text/plain part. This will cause the msg_header to be added as a separate MIME part preceding the rest of the message. If that is the reason, you may be able to adjust the list's content filtering using things like pass_mime_types, collapse_alternatives and convert_html_to_plaintext to ensure the filtered message is a single text/plain part. However, if you want to allow HTML, and or attachments, you will need to ensure that Non-digest options -> msg_header is completely empty, or use a mail client that is better at displaying inline text in line. -- Mark Sapiro <m...@msapiro.net<mailto:m...@msapiro.net>> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
