Plesk can act as a mail server for your domains: you can create mailboxes, change their passwords, set up forwarding and autoresponders, and access mail either through webmail or through a mail client.
Creating a mailbox
- Log in to Plesk and open the Mail tab.
- Click Create Email Address.
- Enter the part of the address before the @ sign and select the domain.
- Set a password, or generate one.
- If required, set a mailbox size limit; otherwise the default for the subscription applies.
- Click OK.
The additional tabs of the same dialog let you configure Forwarding, Email Aliases, Auto-Reply and Spam Filter for this address. These settings can be changed later at any time by clicking the address in the list.
Accessing mail through webmail
Open webmail.example.com in your browser, where example.com is your domain. Log in with the full email address as the user name — for example [email protected] — and the mailbox password.
You can also open webmail from Plesk: on the Mail tab, use the webmail link next to the address in the list.
If the webmail page does not open, check that webmail is enabled: Mail → Mail Settings, click the domain, and select a webmail client in the Webmail setting.
Accessing mail from a mail client
The simplest way to get the correct settings is to take them from Plesk itself: on the Mail tab, click the address and use Connect Devices. Plesk then shows the exact settings for your server, and for some clients can configure them automatically.
If you prefer to enter the settings manually, use the following:
- User name — your full email address, for example [email protected].
- Password — the mailbox password.
- Incoming mail server — the host name of your server, in the form vm00000.sayob.com. Use IMAP over SSL/TLS, port 993, or POP3 over SSL/TLS, port 995.
- Outgoing mail server (SMTP) — the same host name. Use port 587 with STARTTLS, or port 465 with SSL/TLS. Authentication must be enabled, with the same user name and password.
Your own domain can also be used as the server address, but the server host name is the better choice: it matches the server's certificate, so your mail client will not warn you about a name mismatch.
Always use an encrypted connection. The unencrypted ports — 143 for IMAP, 110 for POP3, 25 for SMTP — transmit your password and your messages in plain text. Port 25 is in any case often blocked by internet providers, so use 587 for sending.
IMAP or POP3?
Use IMAP unless you have a specific reason not to. Messages stay on the server, so the same mailbox looks identical on your computer and your phone, and the messages remain available if a device is lost. IMAP also lets you train the spam filter by moving messages into and out of the Spam folder.
POP3 downloads messages to one device and, by default, removes them from the server. It only makes sense if you deliberately want mail kept in a single place.
If you cannot connect
Check that the address and password are entered correctly — the user name is the full email address, not just the part before the @ sign. Compare your settings with those shown in Connect Devices.
If the settings are correct and the connection still fails, the cause may be a blocked port on the network you are connecting from. Try another network, and if the problem persists, open a ticket from your client area.
