I am having trouble while attempting to send a single email to an aol.com user. I get a rejection reply as follows:
Your message did not reach some or all of the intended recipients.

Subject: Test
The following recipient(s) could not be reached:
example@aol.com
Error Type: SMTP
Remote server (205.188.103.1) issued an error.
hMailServer sent:
Remote server replied: 421 4.7.1 : (DNS:NR) http://postmaster.info.aol.com/errors/421dnsnr.html
Tried 9 time(s)
hMailServer
Troubleshooting using AOL's troubleshooting page, rDNS lookup results are:
RDNS Results
DNS Server Response:
www.scanhelper.com
And using NSLOOKUP myself ..
> 60.158.172.99.in-addr.arpa
Server: homeportal
Address: 192.168.1.254
Non-authoritative answer:
60.158.172.99.in-addr.arpa name = www.scanhelper.com
When using telnet,
C:\>telnet mailin-01.mx.aol.com 25
421 4.7.1 : (DNS:NR) http://postmaster.info.aol.com/errors/421dnsnr.html
Connection to host lost.
My hMailServer is set up correctly, is not an open relay, is not used for spam, is not on any blacklists, and so forth.
Any tips on getting AOL mail servers to accept mail? As far as I can tell, everything is being done correctly on my end.
