    I'm having an odd issue with AOL that has recurred 3 times now, with 3 different AOL recipients. Each time, I've sent an email with no problem, then they reply. Then when I reply back, it's returned with this somewhat generic error:

    My Senderbase reputation is Neutral, and MXToolbox shows that I'm not on any blacklists.

    Can anyone suggest whether this issue is on my end or AOL's? Either way, is there anything I can do to fix it on my end?

    Hmm. Thanks, Michael.

    I went through all of the steps listed, and everything checks out perfectly. I've had an SPF Filter, DMARC policy, and DKIM key set up for at least a year, and running "dig" as instructed returned exactly what I thought.

    The only warning from MXToolbox says that Reverse DNS doesn't match the SMTP Banner. I did some research and found references to changing it at /etc/exim.conf, but it's currently the default and I have no idea what should be changed:

    Could this be the reason it's being rejected intermittently? If so, how should I edit it?

    Have you verified the RDNS entry for your IP address matches the hostname of the server?

    Thank you.

    I did, and MXToolbox confirmed it.

    I don't suspect the SMTP banner notification would result in AOL blocking your email. I suggest requesting they delist you by contacting them directly:

    Thank you.
