Some servers support command referred to as nomail or postpone. This command allows users to suspend their delivery of a particular email list. This server does not support the nomail or postpone commands. Therefore, if you want to turn off mail while you're out of town, you must unsubscribe from the list, and then subscribe again when you return. If you are using a vacation program or "mailbot", make sure it is disabled. If your vacation program automatically responds to list postings, your subscription to the mailing list will be cancelled.
