size all recipient or none will match and so the recipient list in the mail
will remain untouched (all matching or none matching).

Not sure if I get your point... I would handle this like:
<servlet match="[EMAIL PROTECTED]"
class="MiniListserv">
<listName> James </listName>
<userListRepository> file://../var/users/james/ </usersListRepository>
<moderator> [EMAIL PROTECTED] </moderator>
...
</servlet>
<servlet match="[EMAIL PROTECTED]"
class="MiniListserv">
<listName> Town </listName>
<userListRepository> file://../var/users/town/ </usersListRepository>
<moderator> [EMAIL PROTECTED] </moderator>
...
</servlet>
Your mail will be splitted on first match and a Mail object with only
"[EMAIL PROTECTED]" as recipient will be send to the first mailet.
Since you are subscibed on that list the mailet will return the Mail with a
list of all subscibed as recipient and a footer added at the end of body.
The second mailet will receive a Mail with only
"match="[EMAIL PROTECTED]" as recipient but since
you're not in the list it will bouce back the mail to you with an error
message and return null.
The last recipient will not match any condition and so will reach the end of
the pipe where the last mailet will bounce it back to you.
So the only thing I'm asking to a mailet is to handle all recipient it
declare to be able to handle.
Is that so bad?
