But having a special folder for a mailing list has at least one more benefit in KMail: it gives you an easy way to write a message to the list. Each folder in KMail can be associated with a list address, and composing a message to this address is simple via the menu.
To make it easy to post to a mailing list in KMail:
- Click with the right mouse button on the folder that holds the mailing list's messages.
- Select Properties....
- Make sure Folder holds a mailing list is checked.
- Enter the email address messages to the list must be addressed to.
- Click OK.
Now you can compose a message to the list by selecting Message | New Message to Mailing-List from the menu in KMail.
