    I'm investigating how can I set up an email server in order to host two domains on centminmod and send the emails of both through this email server.

    I already looked for email hosting but they are quite expensive since they charge per mailbox.

    Then, I found Zimbra:
    Setting Up Zimbra Collaboration Suite (ZCS) on RHEL/CentOS 7/6

    Has anybody tried it or knows if it will allow me to reach my goals?

    What is your mail volume per day? on those domains combined?
    As Zimbra is Collaborative software, it its a bit of a heavy load for the mail task only.

    If it is not mission critical and not too much of volume, I can recommend Mail in a box in advance. In addition to the default mail components. Mail in a box offers:

    Thanks for the info. I'm looking for something easy to manage like cPanel email. I don't send too much emails so I don't need an expensive email service

    Zimbra is not easy to manage in compare to cPanel, Mail in a box or Centminmod.
    And expensive for low email volumes (For single server installations, a minimum of 8GB of RAM is required.)
    Mail in a box is a bit like Centminmod.
    Rent a VPS server, follow the instructions, add a domain (with users), and you're ready.

    Follow this setup guide or the video edition of the setup guide below and you are all set and done.



    Afterwards you can manage your server via the admin panel.

    As i can see on the video he uses ns1 and ns2 nameservers for the domain.

    If i use Cloudflare for my domain how can i set that to work?

    Also hostname and main domain will point to the main server....

    Confused... :-(

    Mail in a box uses her own nameservers. You can use your own external DNS.
    But thats not recommended. There aren't that much providers that could support TLSA Records for DANE.

    Cloudflare isn't recommended as it doesn't support the DANE protocol yet.
    But you can still use CloudFlare's DNS without DNSSEC or DANE TLS.

    In theory, but I did not test that.
    It also has little use because Mail in a box is focused on safety and security.
    And that, of course, is largely gone by not using DANE.

    If you still want to use external DNS. Then just setup your server. Surf to the admin section via the servers IP address /admin, tap on System > External DNS and copy all the DNS records to your external DNS provider.

    Finally the hostname and main domain are the same apart from the fact that you can only enter the admin web panel via the hostname. In short the hostname/subdomain is for management.

    Hopefully this will help.

    Hi Bassie,

    I hope you will be able to give me some guidance,
    I currently have my domain pointed to 158.69.215.142 (vps1) which is the server where I want to store the website. However, I'd like to send emails through 158.69.215.142 (vps2) where I installed mail-in-a-box.

    This is what I've set in CF:
    upload_2017-4-27_12-39-30.png

    However, I'm unable to pass all Mail-in-a-box checks:
    upload_2017-4-27_12-40-20.png

    Could you please let me know if I'm doing anything wrong?

    Please remove your ip address (plain text). As it could be scraped by spambots.
    It seems that your domain has HTTP proxy (CDN) and DNS enabled.

    So not only your DNS but also traffic will go trough Cloudflare.
    You need to use the DNS feature only, in case of Cloudflare, otherwise your traffic is proxy-ed and can't reach your mail server. Also don't forget to setup Rdns (reverse DNS) at Linode, otherwise your mail will be marked as spam.

    P.s. you will never pass all checks because you are using external DNS services.
    Please keep that in mind.

    Hopefully this will help.

    great, thank you! it worked :)

    I'm still trying to decide which one I should take, if zoho or mail-in-a-box.
    I'm planning to host 4 email accounts so zoho will cost the same as a vps for mail-in-a-box.

    Setting my own box will do the same as Mandrill/Mailchimp email service is? I'm trying to understand if I'll have the same server/email validation I get with Mandrill.

    zoho, mail-in-a-box, Mandrill and Mailchimp?
    Whole different software and business. What is the purpose of the mail you want to send?

    Forum notifications. They are usually marked as spam by members and I don't want to compromise the entire server IP just because they are too lazy to enter to their account and disable email notifications

    What is your Mail volume per day?
    And what is the purpose and subject of your forum? As mail providers are very strict in accepting mailing.

    Arround 5000 emails per day, they are just forum notifications (conversations or replies)

    5000, you should have told that before. All own mailservers without a good and long lasting reputation.
    Are easily marked as spam when sending low quality mails i.e. notifications over and over again. (I.e. A comment on the forum has been posted, click here to go review.)

    I'm sending that quantity of emails using WHM/cPanel and didn't have any issues yet. Guess I was lucky enough?

    Could be. You do not know exactly how Gmail or Hotmail established the reputation of your server, domain, ip etc.

    But I know examples of practice where 200 or 500 low quality forum mails per day are already too much. Building a reputation with a domain, ip etc can take a very long time.

    For more info surf on the keyword Gmail postmaster tool of Hotmail postmaster tool.

    In that case does it matter the server IP or the domain? If it's the domain reputation will still
