IMAP, POP and SMTP settings

General information

POP or IMAP?

To read your emails from your computer, smartphone or tablet, there are two protocols:

  • POP Email: allows you to read emails on one device (emails are downloaded to your computer and deleted from the server).
  • IMAP allows you to read emails on multiple devices.

We recommend that you use the IMAP in all cases.

SSL, TLS, StartTLS?

SSL, and its replacement TLS, are encryption protocols that make it possible to prevent a third party from intercepting data transiting on a network.
In the context of email servers, this ensures that your password or emails cannot be intercepted by a malicious person when you connect to our servers to read or send emails.

Your password can still be stolen via a virus installed on your computer, or via a phishing page.

StartTLS, simply put, is a way to use an encrypted connection, on a port normally reserved for an unencrypted connection. If the server does not offer encryption, the connection will still be established, but not encrypted.
This simplifies the configuration of email software and indirectly promotes encrypted connections.

Nuxit mail servers support TLS encrypted connections, with or without StartTLS.

Score

Before changing the score, it is mandatory to contact our technical support before changing anything. At that time, we will give you the guide that you must follow.

If you have ordered a shared, performance, or mail package from us, first make sure that the following pointer is present in the DNS zone of your domain:

Type of record Host Priority Data
CNAME autoconfig.domain autoconfig.webmo.fr.
CNAME pop.domain pop.webmo.fr.
CNAME imap.domain imap.webmo.fr.
CNAME smtp.domain smtp.webmo.fr.
MX domain 10 mx.webmo.fr.
MX domain 20 mxsecondary.webmo.fr.
TXT domain v=spf1 ptr include:spf.webmo.fr ~all
TXT domain v=DMARC1; p=none

If your domain points to our DNS, you need to see, or modify the zone as follows:

Do not hesitate to consult our guide to add DNS entries.

Common mistakes

Unable to move mail to the sent messages folder or recycle garbage can

This error is related to an incorrect setting of the "IMAP path".
To set it up, you need to tell your email program to use an IMAP path starting with INBOX.

Error 550 - relay not allowed

This error occurs when password authentication is not applied for the connection to the outgoing SMTP server.
To solve it, you need to specify explicitly  to your email client to use a authentication by password for the connection to the outgoing SMTP server.
