Lyris supports most standard list server email commands. Also, Lyris can accept multiple, differing versions of the same command.
For instance, the "subscribe" command can be written as any of these:
subscribe
subscribe <listname>
subscribe <listname> my name
subscribe
<listname> <new-user-password>
The <listname> can be omitted if the user sends to the "listname-request" email address.
The following commands are currently supported by Lyris:
subscribejoin
unsubscribe
signoff
leave
review
stats
set
query
confirm
list
purge
which
search
helpinfo
In all these cases, the user can substitute the first three letters for the command ("sub" for "subscribe", etc.)
