bug with certain addresses

While my first message on this issue waits for approval from the mailing list
admin (don't know why) I send a second solution for the bug with addresses
like [email protected] or [email protected]. Such addresses cannot be
subscribed because the following line in rc.request matches if the subject
line contains "subscribe [email protected]".

 * -100^0 ^Subject:(.*[^a-z])?(Re:|erro|change|problem|((can)?not|.*n't)\>)

I would suggest to modify the third condition line of the recipe

 *  100^0 ^Subject:[  ]*archive

to

 *  100^0 ^Subject:[  ]*(archive|(un)?subscribe)

My first solution (which could be come late if the list admin is on holidays)
suggested  to modify the first regex in brackets of the first condition line,
removing the .* greedy regex, but this would weaken the filtering capabilities
for non administrative messages.
