Need proper dkim, domainkeys, spf, and sender id records for server
I have a dedicated server that is running VPS software. (the server runs 'one' main cpanel server, and another 'server' that is used for a qmail server.)
I have 3 domains on this server that send out regular member emails. One of these 3 domains sends some email from the 'cpanel' server, mydomain.com, but most of the emails for that site go out thru the qmail server which is named server1.mydomain.com.
I'm honestly not sure if these records are done by 'server and ip' or by each domain, so pardon me if my wording is not correct.
My server is named "myserver.com", my other 3 sites are named "myserver1.com, myserver2.com, and myserver3.com. The qmail server that is associated with myserver1.com is named server1.myserver1.com"
The 'main' server version is CENTOS 6.3 x86_64 virtuozzo – hosting WHM 11.34.1 (build 7). Not sure on the details of the server that is primarily for qmail.
I am looking for the following:
1. proper dkim, domainkeys, senderid, and spif records for these 3 domains, as well as the emails sent from the qmail server which only applies to one domain name, verifiable by a reputable online tool such as verifier.port25.com.
2. a list of all files modified during this process.
3. step by step instructions on how I can SSH into my qmail server and send an email to firstname.lastname@example.org, as well as retrieve that email to see the results. (I can easily send an email from my 'cpanel' server, but my qmail server doesn't have cpanel so I have no clue how to do this.
