    I have checked my IP for any blacklists, and my IP is clean. Is it because of the [email protected]? If so, how do I change that? Thanks

    The company in question, shaw.ca, may have their own list. I would suggest contacting them directly to see why your IP has been blacklisted.

    1. Check senderbase.org if you have not already.
    2. If your mail server is configured per the snippet above to say that it is "domain.com" and your IP is not in fact showing up with a reverse DNS PTR associated with "domain.com", then many mail servers, not just Shaw, will reject you. Fix it.

    You want your mail server to freely announce to any mail server it connects to exactly who it is.

    - set your hostname correctly, if not already done so; a fully qualified domain name should be what your mail server announces itself as to others
    - ensure your mail server's IP has a PTR (reverse DNS) entry pointing to that fully qualified domain name

    In senderbase, it says my rep is poor.

    How do I do that? I am using whm/cpanel. Thanks

    cPanel will handle the banner and hostname as it should. You'll probably want to make sure you have proper forward and reverse setup for the domain/server though.

    step 1. whatever the real hostname of your machine is (type 'hostname' from an ssh prompt, or search for hostname in WHM) should resolve. so if hostname is blah.server.com, you should be able to ping that, and have it work. This is forward DNS.

    step 2. the main IP of your machine should also have DNS setup for it. This is something your datacenter will probably have to do for you. You can verify this by going to a commandline and typing 'nslookup <hit enter> 10.10.10.10 (or whatever your ip is). It should return something and preferably it should match the hostname of your server. This is reverse DNS.

    If those two things check out, you may have other problems such as spammy scripts and/or users.

    It seems that hostname and rdns for the mailserver are not set correctly.

    You need to set A record for the hostname, you can do it from WHM.
    Also set rdns for your mailserverIP, your DC can assist you with this.

    Also it will be better if you can check the server for any mass mailing scripts.
    A poor reputation for the mailserver IP at the senderbase.org implies that the mail traffic is very high in the server.
