Question: I am subscribed to a Mailman list. When I use MS Outlook to read messages sent to the list, all of the messages appear to be from listname-bounces@mailman.u.washington.edu on behalf of the original person who sent the message. Why is that and do other people see the same thing?
Answer:
When a message is sent to a Mailman list, Mailman adds a Sender header that looks like this:
Sender: listname-bounces@mailman.u.washington.edu [listname-bounces@mailman.u.washington.edu] On Behalf Of name of senderSome email programs such as MS Outlook read this Sender header rather than the original From header but label it as the From header. Only people using MS Outlook (or other programs that behave in the same way) will see the From line in this way. Most programs will display the correct From line with the original sender's name and address. Date: 08/2004 Author: R. Skiver Thompson
