How to Set Up Your Email Client to Work with Email Hosted by Gandi

Grouped here is some information about the various standard settings recommended to set up your e-mail clients, regardless of the client or the operating system you use.

This will enable you to use your own choice of software to send and receive email from your domain’s Gandi Mail addresses.

General Configuration & Settings


  • The most common problem for users who can’t log in is that they don’t use the full email address as the username. Be sure you follow the settings instructions carefully.

  • If you use an internationalized domain name, or a domain name with international characters, you may need to use the punycode version of the domain with some email clients. You can look up the punycode for an international domain here.

  • The POP account enables you to “download” messages from a server to a computer. This is the simplest and most common setting for an e-mail client.

  • The IMAP account enables you to access messages directly on the server, just as if you were going to Emails are not stored locally with an IMAP account, which makes it useful if the mailbox is synched between several clients (computer, smartphone, etc.).

  • TLS: TLS is a more recent and secure protocol than SSL. Nevertheless, it appears as though some e-mail applications have trouble managing TLS and display a certificate warning during during send/receive. If you get such a warning while using TLS, please consider upgrading your email application.

  • SSL: We still support SSL (3.0), though this protocol is no longer considered as being secure. We therefore recommend that you use TLS.

  • Yourdomain.tld: when you see this expression, replace it by your own domain name (as in For your information, TLD means and represents your domain’s extension (.com, .net, .org, .fr, .eu,, …).

  • The “forwarding” cannot be configured on an e-mail client, as opposed to your mailboxes, for the very simple reason that they forward e-mails to a real mailbox (the e-mail you have with your Internet service provider, or a Gmail, Hotmail or Yahoo account, for example).

POP/IMAP Account

This is for incoming email.

  • Incoming server name:

  • Port: leave the default setting (110 for POP, 143 for IMAP, 995 for POP SSL, or 993 for IMAP SSL).

  • TLS or SSL: Yes

  • Username: this is the entire e-mail address (including @yourdomain.tld)

  • Password: provide the password you defined when creating the mailbox

SMTP Account

This is for sending email.

  • Outgoing (SMTP) server name:

  • Port: 25, 465 (with SSL) or 587 (with STARTTLS)

  • TLS or SSL: yes

  • SMTP Authentication: yes, using the same settings as for the POP / IMAP account


You are absolutely able to use your Internet Service Provider’s SMTP instead of Gandi’s. In that case, remember to disable SMTP authentication, as your Internet service provider can identify you through your connection’s IP address automatically.

SRV Records

We recommended adding the following SRV records to your domain name’s DNS records, if they have not already been added automatically. These records allow email clients and servers to find Gandi’s IMAP/POP and SMTP servers in a standard way.

_imap._tcp 10800 IN SRV 0 0 0   .
_imaps._tcp 10800 IN SRV 0 1 993
_pop3._tcp 10800 IN SRV 0 0 0   .
_pop3s._tcp 10800 IN SRV 10 1 995
_submission._tcp 10800 IN SRV 0 1 465
