Choosing an Email Solution

In addition to creating unlimited email accounts for your domains, you can set up mail forwarding, create mailing lists, manage user permissions, and access your email with either an email program or in a browser from any computer.

1&1 IONOS Webmail is an excellent solution for most cloud users.

Self-Hosted Mail Server

If you prefer to host your own mail server, you will need to install and manage the software. You will also be responsible for maintaining the server, installing updates, and handling any security issues.

Self-hosting is an option for users who want to install and manage custom scripts or programs to interact with their mail server.

Mailing Lists

Mailing lists are a good way to stay in touch with your customer base, and notify your users of sales, coupons, updates, and other news.

1&1 IONOS Webmail includes mailing list functionality. To set up a mailing list, log in to your 1&1 IONOS Email Control Panel and click on More Options > Create Mailing List. For more details, see the Article Set Up a 1&1 IONOS Mailing List.

Self-Hosting a Mail Server

If you have a firewall, you will need to allow access to the following ports:

  • 25: SMTP
  • 2525: Alternate SMTP
  • 110: POP
  • 143: IMAP
  • 465: Secure SMTP (SSL/TLS)
  • 587: Suggested alternate SMTP
  • 993: Secure IMAP
  • 995: Secure POP

For more information about using a firewall on a Servidor Cloud, consult our documentation on the topic.

For security reasons, port 25 is disabled on Servidor Cloud accounts. You can contact Customer Care to enable port 25 for your contract. However, we recommend using port 587 instead of port 25 for SMTP. Port 587 is enabled by default, you will simply need to add a Firewall Policy to allow access.

For tutorials on setting up an email server, see the article for your operating system:

DNS: Configure the MX Record

In order to use 1&1 IONOS Webmail, you will need to update your domain name's MX records.

Log into the 1&1 IONOS Control Panel and go to My Products > Domains.

Click the Options icon for the domain name you want to edit.

Manage Email on a Servidor Cloud: Options

Click DNS Settings.

Click Other mail server

Manage Email on a Servidor Cloud: DNS Settings

Enter the mail server record(s) and priority.

We recommend you select Set 1&1 IONOS mail server as backup MX. That way, if your mail servers fail, email will still be delivered (to a 1&1 IONOS webmail account) instead of being bounced back to the sender.

Mailing Lists

Due to the risk of mailing list messages being incorrectly flagged as spam, we strongly suggest the use of third-party mailing list services like MailChimp or Constant Contact. These services are designed to ensure that your mailing list messages will follow the correct policies and procedures to prevent your domain name or IP address from being added to an anti-spam blacklist.

Sending Email From an Application on Your Server

Even if you prefer to set 1&1 IONOS webmail as your mail server, there may be occasions when you need an app or script on your server to send email. For example, you may have a Contact form on your website which sends you an email when someone fills out a form on the site.

For security reasons, the SMTP port is blocked by default with the Servidor Cloud firewall. You will need to allow access to the following ports in order to send email from your server:

  • 25: SMTP
  • 2525: Alternate SMTP
  • 465: Secure SMTP (SSL/TLS)
