Convenience Addresses are email addresses that can be created so your list users can use firstname.lastname@example.org for the list, rather than email@example.com. Thus, the lists portion is removed in convenience addresses.
Examples of convenience addresses
The following convenience addresses are created when adding a Discussion List named mylist to a domain of example.com.
All addresses in this first column forward to the corresponding Discussion List email address:
|Convenience address||Discussion List address|
