    I have no idea what I'm doing and need assistance. Apparently we are blacklisted as some sort of spam source with our email account and I need to change the outgoing SMTP to our ISP's address. I usually use cpanel to check/write/and delete emails. My host said I should be using Outlook (not sure why), but I've never found it necessary.

    I know how to change the outgoing SMTP in Outlook, but how does it have any affect on my settings in cpanel (or my host's mail server)? I want to be able to change the port as well. Is there any way to manually do this in cpanel? I am very new to this and am not a spammer. We have a small business and the emails we send out keep getting returned to us.

    Help!! :(

    It is suggested that you find and eliminate the root cause of the problem. Get your mail server IP and check it against more than 100 known blacklists using Email Blacklist Check - See if your server is blacklisted. If it is blacklisted somewhere then follow the respective procedure to get it de-listed.

    However, as a temporary solution you can change the IP your mail server uses by editing the TRANSPORT section in the file /etc/exim.conf to any other IP on the server. Make sure that the rDNS is set as well.
    Note : Do not attempt this if you do not have hands-on experience.

    By the way, do you get any errors/bounce backs? If yes, what do they say? Have you checked the error logs located at /var/log/exim_mainlog ?
