AOL users not receiving emails from my site

[napccomm]

Hi there,

Recently, i was talking to a fellow user on my forum (notanotherpccommunity.tk), and he was saying that he wasn't receiving emails from the site. I took a look at the mail logs (checking my default email @notanotherpccommunity.tk), and it had a ton of mail rejection messages all about the mail server's IP being blocked by AOL. I have an example below (note, some parts were redacted).

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

(redacted)@aol.com
SMTP error from remote mail server after end of data:
host 198.91.80.251 [198.91.80.251]: 571 5.6.0 id=10887-18 - Rejected by MTA on relaying, from MTA([127.0.0.1]:10030):

So, can an x10Hosting SysAdmin ask AOL to unblock the x10 server "level"? Sorry if i sound like a noob here.

Thanks in advance;
