Sending Messages
Sending a message to the members of an e-list is almost exactly like sending any other email message.
You simply put the e-list address in the To field, like this:

Be sure to include the hyphen and the letter L at the end of the list name. In this example, it's
sheep-shearing-L
not
sheep-shearing
Messages should be kept as small as possible. Many people access their email through slow connections or small devices (like cell phones), or have mailboxes with size limits. Instead of sending attachments to the entire list, put the file on a web site for people to retrieve. If you post a message larger than 1 MB (including attachments), it will be returned to you with an error message.
What happens after you send your message depends on the way the list administrators have set up this e-list.
- Unmoderated lists: messages are delivered to all list members exactly as submitted.
- Moderated lists: each message is reviewed by a list administrator, who can reject messages if they are not appropriate for this list. The administrator may also edit your message before sending it on to the list.
- Announcement lists: only administrators can post messages to these lists. If you try to post to an announcement list (and you don't have administrative privileges), you'll receive an error message.
