AOL updated the way they authenticate emails and this may cause delivery issues for automated email services such as Mandrill, the delivery service Wiredrive uses to send your presentations. This does not just affect Wiredrive users, but extends to any application that uses a delivery service
To avoid this AOL has posted an article outlining what you must do to receive messages sent from automated services.
We recommend avoiding use of AOL all together as there are more reliable services such as Gmail that will ensure a higher percentage of deliverability. If you do use AOL and cannot move to an alternative, we recommend whitelisting the Wiredrive delivery domains via the AOL Postmaster.
