I just tried out Acymailing (free) with the optin and optout actions. First I subscribed to a list and confirmed subscribing.
Then I went to the laptop of my friend, typed in the mailaddress of the fresh subscription and unsubscribed. The mailaddress has been unsubscribed immediately....
...and this happened, although a wrong Name was used in combination with the mail address
...and this happened, without an email to the subscriber, asking wether he had done the unsunscription and would confirm it.
Anyone, who guesses, that someone would have a subscription on a list could unsubscribe this person without this person would come aware of this.
Is there something wrong with my configuration in Acymailing? What should I change, to prevent misusing unsubscriptions?
