Email Hosting Setup in Plesk

Creating an email account

Open the subscription → Mail → Create Email Address.

Enter the local part (e.g. hello for hello@yourdomain.com).

Set a password. Use the generator for something strong.

Set a mailbox size quota (MB) or leave unlimited.

Click OK.

Webmail access

Plesk includes Roundcube webmail:

https://webmail.yourdomain.com

Or via Plesk panel → Mail → Webmail.

Email aliases

An alias delivers mail to an existing mailbox without a separate login:

1. Open the email account → Email Aliases → Add Alias
2. Enter the alias address
3. Click OK: mail to the alias goes to the main mailbox

Forwarders

Forward all mail from one address to another (including external addresses):

1. Open the email account → Forwarding → Enable Mail Forwarding
2. Enter the destination address
3. Choose whether to keep a copy in the local mailbox
4. Save

Catch-all address

1. Subscription → Mail → Change Settings
2. Enable Redirect unmatched mail to address
3. Enter the destination
4. Save

Spam filtering (SpamAssassin)

Plesk uses SpamAssassin for spam filtering:

1. Open the email account → Spam Filter
2. Enable spam filtering
3. Set the sensitivity (score threshold): default 7 is reasonable
4. Choose action: mark subject, move to Spam folder, or delete

All outbound mail from your RemarkableCloud server routes through MailChannels for reputation protection. This applies regardless of which control panel you use.

Mailing lists

For newsletters or group email:

1. Subscription → Mail → Mailing Lists → Create Mailing List
2. Set the list address and administrator email
3. Add subscribers
4. Send to the list address: Plesk distributes to all subscribers

Mailing lists in Plesk use Mailman. For bulk marketing email (hundreds/thousands of recipients), use a dedicated service instead.
