Problem with blacklisting

[CarlosBurgos]

After solving the problem of blacklisting, are again returned emails.

My previous thread is here: http://forum.parallels.com/showthread.php?296771-Change-my-domain-to-avoid-being-blacklisted
I have checked the previously edited files, and are correct.

I have found that I have two IPs on my plesk server. The one on the blacklist is not corresponding to my FTP server, or web.

Why that is listed second IP blacklisted?

Thank you.

Hello,

If your IP is blacklisted in CBL, Check that in CBL lookup and you will get information of your IP

http://cbl.abuseat.org/lookup.cgi

Yes, I have 82.223.124.105 listed on CBL. But other IP 82.223.114.231 is not listed.

Why I have two IP in my plesk, and how can I erase the blacklisted?

I find http://mxtoolbox.com very useful for checking mail servers and blacklisting.
I noticed you don't have a SPF record published for your domain....

v=spf1 a mx ptr ip4:82.223.124.105 a:mail.centropuntocero.com -all

Should be good.
Have you set up DomainKeys?

If memory serves, Qmail can only send from one IP address, you'll need Postfix to send from both.
Hence only one IP address getting blacklisted.

And if you are using your domain registrar for your DNS remember to add your SPF and DomainKey records there.

Hope that helps
Kind regards
