Mail drops into spam box of yahoo from a single domain

[lampscholar]

The mails are reaching from all my domains (hosted in same server) to yahoo properly when tested. But all the mails from a particular domain out of many domains hosted in the server sent to yahoo reaches yahoo's spam box. The host says that this problem is nothing to do with them since it works fine for all other domains. Suggestions on this are welcome.

You will have to contact the recipients and make confirm that your server IP address from where you are trying to send mails is not marked as spam.

yahoo may have identified a lot of mail from this domain to their users and might have marked it as possible spamming.

ask domain owners to contact yahoo, there's nothing your host could possibly do.

You may also want to consider turning on DomainKeys support for the domain in question. Yahoo was part of the implementation of DomainKeys, so they are more likely to not spam list a domain signing emails with it.

The command to add that support onto an account would be the following in root shell:

/usr/local/cpanel/bin/domain_keys_installer username

Replace username with the username in quesiton. This would add the DNS entry for DomainKeys for every domain on that account.

If you wanted all accounts on the server to have the entries, you could run this command:

for i in `ls /var/cpanel/users` ; do /usr/local/cpanel/bin/domain_keys_installer $i ; done
