Multiple emails confirming opt out

[VitorFF]

Hello everyone,

We are having a problem where if someone opt's out of a mailing it receives several emails confirming the opt out.

I.e. a contact clicks the opt out link and then goes to the opt out page. After confirming the opt out it receives an email saying so. A couple hours later (2 to 3 hours) it gets another email confirming the opt out.

Has any one else had this or a similar issue? Any ideas on what may be causing this.?

Thank you guys,
