Can't send to AOL?

[ludatbooick]

Hi everyone. I just installed Roundcube with hmailserver (with built-in MySql), and PHP 5. The application seems to work fine, i can send and receive mail and all that jazz except to AOL addresses. It is no problem to receive from AOL but I tried three diff addresses and get an undeliverable back in my inbox. Anyone run into this before? I looked on the forum but didn't find any info on it. Thanks!

Edit: I cannot send to MSN or Hotmail either. Any help would be appreciated!

I did some research and it seems that AOL will not accept email from a residential (dynamic) IP (even though my ISP is cable and IP doesn't change it is still not labeled as static). Is there anyone else hosting their webserver/emailserver from a non-business ISP account having this problem? Thanks!

I am running a mail server from a residential, DHCP assigned address. I ran into the same problem you guys had, but there were a lot more domains that rejected mail than AOL.

The list of ways the mail servers try and reduce spam is as long as my arm, but in this particular instance, it appears reverse DNS (PTR record) lookups will identify that you are using an IP from your ISPs dynamically assigned pool, and will therefore block you.

Personally, I'm running Postfix on Fedora Core 6, and simply configuring it to relay outbound mail through the ISP mail server solved my issue. I just had to add: relayhost = [myisp.mailserver.tld] to the main.cf config file.

You'll have to see how to do it for your respective MTAs, but then you won't have any problems sending mail to any domain because in essence the mail will still be coming from your ISP mail server.

Hope that helps!
