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.
Warning: Switching to a different mail server is only recommended on fresh Plesk installations. On servers already used to host live customer accounts, switching to a different mail server is not recommended and will result in the loss of mail settings and data. If you must change the mail server on a live Plesk installation, we recommend notifying your customers in advance and advising them to save their mail (you will not be able to restore mail from Plesk backups after the mail server change).
To Switch to a Remote SmarterMail Server:
- Go to Tools&Settings and click Server Components. Find the "Mail Server" section and click Remote SmarterMail Server (not configured).
- 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).
- (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.
- Click Ok. If a connection to the remote SmarterMail server could be established, it will appear in the list of available mail servers.
- To complete the mail server change, click Mail Server, select the "Remote SmarterMail Server" option from the list, and click Ok.
- 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.
- (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.
