Setup mail server that may send emails to inbox

You can enable SPF and domainkeys in cPanel > Email Authentication area to improve your domain's scoring and reduce the likelihood of being tagged as junk or spam.

If you want to enable it for all domains on the machine, you could run this command:

Code:

for x in `ls -A /var/cpanel/users`;do /usr/local/cpanel/bin/domain_keys_installer $x && /usr/local/cpanel/bin/spf_installer $x ;done

If you want all domains to have it on account creation, you can do the following:

Code:

touch /usr/local/cpanel/scripts/postwwwacct
chmod +x /usr/local/cpanel/scripts/postwwwacct

Put the following into the /usr/local/cpanel/scripts/postwwwacct file:

Code:

#!/usr/bin/perl

my %OPTS = @ARGV;
$ENV{USER} = “$OPTS{‘user’}”;
system q(/usr/local/cpanel/bin/domain_keys_installer $USER);
system q(/usr/local/cpanel/bin/spf_installer $USER);

Next, is the main server IP being used to send the emails? If so, then check that the server's hostname matches the reverse DNS (rDNS) for the IP:

Code:

hostname -f
dig -x IP# +short

Above please replace IP# with the server's main IP number.

Finally, can you state if all servers are receiving the domain's messages to spam or junk or only some servers? If it is a server like yahoo or hotmail, then having SPF records, domainkeys and a matching rDNS with the hostname should help.

 

If the domain is sending from the main IP of the machine, then you need the rDNS for the IP (the PTR record for the IP) to match the hostname. Hosts typically perform sender verify and, if the hostname doesn't match the IP's PTR record for the reverse DNS, then they will often either reject the message or place it into spam.

Does the hostname match the return for the dig for the IP?

 

The IP you noted does not have any PTR record setup for it for rDNS at all. That is why if you put in "dig -x IP# +short" you won't even get a reply as there is not answer section showing. Compare that to this Google IP when you do the same thing:

Code:

# dig -x 74.125.227.83 +short
dfw06s07-in-f19.1e100.net.

Any IP that doesn't have a response with +short added to the IP dig doesn't have a PTR setup. Your emails will most definitely go to spam if you don't have a PTR record for the IP. Only the provider of the IP can set the reverse DNS (PTR) for the IP. You will need to contact your hosting provider, datacenter or NOC, whoever provided the IP, to ask they setup the IP to match your hostname.

 

You are always welcome to open up a ticket to us for us to check everything is properly configured per how you would like it setup. If everything is properly configured and it still is marked as junk by hotmail, you'll have no choice but to contact them directly to ask why.

You can submit a ticket in WHM > Support Center > Contact cPanel or using the link in my signature. Please post the ticket number here upon sending one to us. Thanks!

 

I rather not close the thread as it would be better for anyone else reading it to know the results of the ticket after it is resolved.
