There are two ways to access a mailbox for sending and receiving email
messages:
- Use a web browser to connect to the webmail interface.
- Set up and use an email client program on your computer.
Setting up Email Clients
Plesk can automatically set up certain email clients (for example, Microsoft Office Outlook,
Mozilla Thunderbird, and others). This feature is called
mail autodiscover. It automatically configures necessary settings
(mail protocols, mail servers, ports, and so on) and you do not need to
specify them manually. However,
not all domain configurations support mail autodiscover.
If your domain does not support mail autodiscover or you want to use
mail clients other than Microsoft Office Outlook and Mozilla Thunderbird,
set up an email client manually. Typically,
you will need to specify the following settings:
-
Username. In this field, specify your full email address. For
example, [email protected]. - Password. Most likely, the password to your email account.
-
Mail server protocol. This property defines whether you want
to keep copies of messages on the server or not. To keep the
copies on the server, select the IMAP option. If you do not
want to keep them on the server, select POP3. Selecting IMAP
will also allow you to train the SpamAssassin spam filter on email
messages you receive, if SpamAssassin is enabled on the server. -
Incoming mail server (POP3/IMAP). Type your domain name.
For example, example.com. The POP3 port is 110. The IMAP port is
143. -
Outgoing mail server (SMTP). Type your domain name. For
example, example.com. The SMTP port is 25. This server requires
authentication.
To see the settings necessary for setting up an email client,
go to Websites & Domains > the domain whose email you want to access via an email client > Mail Accounts > the 
icon.
If the default mail settings shown in the “Manual Setup” section do not suit your customers, you can edit the text of the section…
