Implementation of the email service.

1.- Request through the form on the main page the registration of the corporate email.
You will receive an email with the URL, configuration parameters and access credentials (Email + Password).
2.- Modify the DNS records at your domain registrar as indicated in the section below.
3.- Configure the mail sending and receiving parameters of your email applications.

2.- Modification of DNS records.

In the DNS Configuration section of your domain registrar you must add the following records.

MX record.

MX records indicate which host is in charge of processing mail for your domain.

SPF record.

SPF is a protection against address spoofing when sending email. It identifies, through domain name registrations, authorized SMTP mail servers for the transport of messages.

DMARC record.

DMARC is a standard that seeks to unify current SPF and DKIM validations, "guiding" your way to email services such as Gmail or Outlook in the event that validation fails in an email. Complements SPF and DKIM. This record indicates what to do when the previous records fail, in order to take the necessary measures as soon as possible.

DKIM registration.

DKIM allows you to “sign” the mail with your domain using public keys indicated in the zones of your domain. In this way the recipient is sure that the email has been sent from your server and has not been intercepted and / or forwarded from another unauthorized server.

You will receive these parameters in an email when requesting the new email address(es) from the form on the main page

3.- POP3, SMTP and IMAP settings.

POP3, IMAP, and SMTP each have a role, read on to see which settings best suit your particular email needs.

What is POP3 and what are the default POP3 ports?

Post Office Protocol version 3 (POP3) is a standard mail protocol used to receive mail from a remote server to a client of local email. POP3 allows you to download email messages to your local computer and read them even when you are offline. Please note that when you use POP3 to connect to your email account, messages are downloaded locally and removed from the email server. This means that if you access your account from multiple locations, that may not be the best option for you. On the other hand, if you use POP3, your messages are stored on your local computer, reducing the space your email account uses on your web server.

By default we use the port:

• Port 995 – this is the port you need to use if you want to connect using POP3 securely.

You must configure the address box.123mail.es as a POP3 server on port 995.

What is IMAP and what are the default IMAP ports?

Internet Message Access Protocol (IMAP) is a mail protocol used to access email on a remote web server from a local client. IMAP and POP3 are the two most widely used Internet mail protocols for retrieving emails . Both protocols are compatible with all modern web servers and email clients.

While the POP3 protocol assumes that your email is accessed only from one application, IMAP allows simultaneous access by multiple clients. This is why IMAP is more suitable for you if you are accessing your email from different locations or if your messages are managed by multiple users.

By default we use the port:

• Port 993 – this is the port you need to use if you want to connect using IMAP securely.

You must configure the address box.123mail.es as the IMAP server on port 993.

What is SMTP and what are the default SMTP ports?

The Simple Mail Transfer Protocol (SMTP) is the standard protocol for sending mail over the internet.

By default we use the port:

• Port 587 – this is the port used if you want to send messages using SMTP securely over STARTTLS.
• Port 465 – this is the port used if you want to send messages using SMTP securely over SSL.

You must configure the address box.123mail.es as the SMTP server on port 587 or 465.
