Description:
------------
We have mlmmj list but while we are trying to subscribe the list we noticed that a user can subscribe the list multiple times

Test script:
---------------
You can try to subscribe with same email address multiple times to  mlmmj+subscribe@mlmmj.org address and it will send back the confirmation email again and again.

Expected result:
----------------
After first subscription process, it needs to return a message that implies the user already subscribed the list.

Actual result:
--------------
After first subscription process, The list sends the confirmation email every time you send an email to subscription address.

( my use case for mlmmj  is "alias one address to several addresses", subscribe and unsubscribe is done by admin )


I wonder if the duplicate user subscribions result in duplicate addresses in the backend.

@sinanulker386   reporter of the bug  or others who read this:
Are there duplicate addresses in backend?

Who sees sending (resending??) subscribe confirm  upon subscribe request as a nice feature

@stappers,

Yes, the duplicate user subscriptions result in duplicate addresses in the back-end.
For example below is the subscription list on my back-end after I subscribe it 5 times with the same email address: 

/var/spool/mlmmj# cat /var/spool/mlmmj/sohbet/subscribers.d/u                                                                            
user@example.com
user@example.com
user@example.com
user@example.com

For my previous comment it was 4 times. I mistyped 4 as 5.

Persons who did subscribe multiplie times,
do they also get multiple copies of mailinglist postings?

Upon unsubscribe:  Are multiple unsubscribe actions needed?
