Supported e-mail protocols and ports

If you are using an email client program such as Outlook or Thunderbird, for example, you should configure it as follows:

Incoming (IMAP or POP3) and outgoing (SMTP) mail server:mail.your_server.comYou can find your server's host name listed in the upper left corner of your Control Panel.

For outgoing email, you can also use the SMTP server provided by your ISP, if one is available.

For more information on the servers, protocols, ports, and supported functions please refer to the table below:

Server	Protocol	Port		Information
Server	Protocol	Standard	Alternative	Information
Incoming	IMAP	143	-
	IMAPS	993	-	- IMAP with SSL/TLS encryption¹
	POP3	110	1100
	POP3S	995	-	- POP3 with SSL/TLS encryption¹
Outgoing	SMTP	25	587	- Supports encryption with STARTTLS²- Requires logging in with your email address and password
Outgoing	SMTPS	465	-	- SMTP with SSL/TLS encryption¹

SSL/TLS (implicit encryption) is the most secure way to communicate with the server. Encryption is mandatory, and it is established at the beginning of the SMTP session.
STARTTLS (explicit encryption) is a way to upgrade a plaintext connection to an encrypted one. Encryption is optional and is initiated by your email program before logging in.
