reverse DNS failed
Reverse DNS lookup for your IP address is failing. AOL does require that all connecting Mail Transfer Agents have established reverse DNS.
Now I went to www.mxtoolbox.com and typed in my IP Address (12.146.245.34) and it said Reverse DNS failed. My email server is mail.funsunstudio.com Now I can send to just about any other account (only other one that I have had a problem with is roadrunner e-mails). I have a seperate IP address for my website and for my e-mail. Everything looks to be right when I do a dig on my domain as well. This was working for a couple days and then it quit working (without me touching anything).
Here is what postconf -n outputs:
command_directory = /usr/sbin
config_directory = /etc/postfix
content_filter = smtp-amavis:[127.0.0.1]:10024
daemon_directory = /usr/libexec/postfix
debug peerlevel = 2
enable serveroptions = yes
html_directory = no
inet_interfaces = all
local recipientmaps = proxy:unix:passwd.byname $alias_maps
luser_relay =

mailbox sizelimit = 0
mailbox_transport = cyrus
mailq_path = /usr/bin/mailq
manpage_directory = /usr/share/man

mydestination = $myhostname,localhost.$mydomain,funsunstudio.com
mydomain = funsunstudio.com

mynetworks = 127.0.0.1/32,10.0.0.1/32,12.146.245.32/28
mynetworks_style = host

sendmail_path = /usr/sbin/sendmail
setgid_group = postdrop
smtpd clientrestrictions = permit_mynetworks reject rblclient sbl-xbl.spamhaus.org permit
smtpd tls_keyfile =
unknown local_recipient_rejectcode = 550
virtual mailboxdomains = hash:/etc/postfix/virtual_domains
virtual_transport = lmtp:unix:/var/imap/socket/lmtp
I am not an open relay and everything else is working great, I just can't seem to get this reverse DNS problem to start working again. Any help would be appreciated.
