I have a client that is having emails to AOL email addresses bounce. I have read about why this may happen with AOL and it seems to be related to them not accepting email from domains that do not have PTR or SPF records setup for a reverse DNS zone. I called the ISP of my client and had them setup a PTR record and it has propagated. I sent a test email from that domain to an AOL account and it has been about a half hour and the email has not been delivered nor has it bounced. If I went to setup the SPF record do you think that would fix the issue. It appears that this only happens with AOL accounts.
