We just moved our website to a dedciated server and everything is up and running fine. We also send out about 5,000 emails on a monthly basis and the list continues to grow. We currently have one IP Address for our website and want to have a mail server also. We would just send the emails from our new server, but are affraid to use the same IP address because we read about people getting their IP blacklisted. We don't spam, these are all people who have requested our emails, but you never know and would rather be safe than sorry. If we want to create a dedciated mail server, do we just get a new IP address and use the same server or do we have to go with a completly new server? What programs are best for this type of email? Any help or guidance would be great.
If by chance you do get blacklisted (and your web hosting and email server is using the same IP address) then everyone will still be able to access your website. The only thing that is blocked (if you are blacklisted) would be the email only. Not the website.
But if you do want to get another IP address for your email server, then you can still run both IPs on the same server. One for your website, and one for your email server. No real need to get another server unless that one server cannot handle both.
Nothing really wrong with having two IP addresses. Especially if extra IP addresses already come with your dedicated server. Why not go ahead and use them?
It should be noted in the current Release of cPanel 11 that if you set up a dedicated IP you can have the e-mail come from the dedicated IP instead of the standard server IP.
You could for example set up a domain just for mailing your list, add it to your server and then set it up on a dedicated IP. This would prevent your normal e-mail from getting blocked as well.
There are other more involved methods to accomplish this, but the steps I basically outlined are probably the easiest and trouble free way to do it on a server with cPanel, I cannot speak for other control panels.
