. My forum has several AOL users that have turned on subscriptions. When Snitz sends them an e-mail notification of a new post, the e-mail message is refused.
Can I, and if so, how do I instruct the user to adjust their AOL settings to accept the forum subcription e-mail?
Yes. You need an SPF record before you can apply for whitelist status. I'm sure that everyone's experience is different but it solved my problems with AOL.
