Webmail configuration for mobile phone.
General configuration & settings
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 mail.gandi.net. We recommend the use of POP for the very simple reason that emails are not stored locally with an IMAP account, and so you risk losing emails if you run out of storage space or forget to renew.
TLS/SSL: TLS is a more recent secure protocol than SSL. Nevertheless, it appears as though (at least some) e-mail clients have trouble managing TLS, so we recommend SSL.
Yourdomain.tld: when you see this expression, replace it by your own domain name (as in example.com). For your information, TLD means and represents your domain's extension (.com, .net, .org, .fr, .eu, .co.uk, …)
The GandiMail "Forwarding" option 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).
Incoming server name: mail.gandi.net
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: your full e-mail address (including @yourdomain.tld)
Password: provide the password you defined when creating the mailbox
Outgoing (SMTP) server name : mail.gandi.net
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
