Remote SmarterMail Support (Windows)

Instead of using a local mail server, you can integrate Plesk with a
remote SmarterMail server. This enables your customers to send and
receive mail, although with a number of limitations, listed below. You
can use a single SmarterMail server as a centralized mail server used by
multiple Plesk installations.

Important Information and Limitations:

• Only SmarterMail 15 and later versions are supported.
• Mail data from a remote SmarterMail server is not included in Plesk
  backups. You must put a backup/restore scheme in place manually - for
  example, following the practices recommended by SmarterTools.
• After switching to a remote SmarterMail server, some mail-related
  functionality and settings, such as spam filtering, antivirus,
  autoresponders, or black/white lists can no longer be managed from
  Plesk and must be configured on the SmarterMail side. Note that the
  functionality is not lost - just replaced by the SmarterMail
  counterparts.

To Switch to a Remote SmarterMail Server:

1. Go to Tools&Settings and click Server Components. Find the
   “Mail Server” section and click Remote SmarterMail Server (not
   configured).

2. Type in the necessary information about the remote SmarterMail server
   - its hostname, port, and administrator login and password. The
   hostname must resolve correctly, and the port must be accessible from
   the Plesk server (you must make the necessary changes to the firewall
   settings manually).

3. (Optional) For additional security, you can enable the following
   options:

   • Use HTTPS protocol allows only secure connections to the
     remote SmarterMail server.
   • Check SSL certificate when HTTPS protocol is used forces the
     mail server certificate validity check.

   Note that to use these options, you must manually configure the
   remote SmarterMail server to use HTTPS following the instructions
   here
   and
   here.

4. Click Ok. If a connection to the remote SmarterMail server could
   be established, it will appear in the list of available mail servers.

5. To complete the mail server change, click Mail Server, select the
   “Remote SmarterMail Server” option from the list, and click Ok.

6. To ensure that the DNS records of hosted domains point to the remote
   SmarterMail server, update the MX records in Plesk DNS template
   accordingly, following the instructions found here.

7. (Optional) To enable your customers to access the SmarterMail webmail
   from Plesk, click Mail Server, select Remote SmarterMail Web
   Client under “Webmail”, type or paste the SmarterMail webmail URL
   into the Login page URL field, and click Ok.
