What is MailerProtect?
MailerProtect is an incoming MX gateway. It receives email for your domain and forwards accepted messages to your existing mail server.
Who is it for?
Business owners who manage their own email, system administrators, and anyone looking to reduce direct exposure of their incoming mail server.
Do I need to move my mailboxes?
No. Your mailboxes and stored email stay on your existing server. MailerProtect handles incoming delivery before messages reach it.
Will users need to change their email clients?
No. Your existing mailbox access and outgoing email settings can stay as they are. Setup changes concern your domain’s MX records and your server’s inbound SMTP access.
Does MailerProtect hide my server’s IP address?
Your destination server does not need to appear in your current public MX records. Its IP may still be discoverable through other DNS records, historical DNS data, or email headers. Restricting direct inbound SMTP access is an important part of the setup.
Does this protect my entire server from DDoS attacks?
DDoS protection applies to the MailerProtect gateway at its provider’s network level. Other services and any exposed IP addresses on your own server need their own protection.
What happens if my mail server is temporarily unavailable?
MailerProtect queues accepted messages and retries delivery when your server becomes available.
Does MailerProtect handle outgoing email?
This service handles incoming email. You can continue using your existing outgoing mail provider or server.
Are there limits on email addresses or incoming email volume?
There are no plan limits on the number of email addresses or incoming email volume for a connected domain.
Can I connect multiple domains?
Yes. Each domain is €2.99 per month and can be configured with its destination mail server.
