Email an AOL-Email wird abgewiesen. Was kann man da tun?
Ich habe mal bei ein Ticket gezogen. Bin gespannt, ob es eine Antwort gibt.

Reverse hostnames. When emailing users at AOL, the AOL server would respond with a cryptic error message:
521 5.2.1 : AOL will not accept delivery of this message.
This is not one of AOL’s documented error codes. It took a lot of research, but I finally discovered that this is related to the reverse network address. Both AOL and Microsoft require the sender’s reverse hostname to resolve to the sender’s domain name. (Or in the case of AOL, it can resolve to anything except an IP address. If a lookup of your network address returns a hostname with the network address in it, then AOL will reject the email.) If you have a residential service (like Comcast or Verizon), then the reverse DNS lookup will not be permitted — you cannot send email to AOL directly from most residential ISPs.

Also – gab es eine Antwort? Nein.
