Setting up a Catchall filter for a domain in the ISPConfig control panel.

Introduction

• Email Catchall is a feature that redirects messages sent to nonexistent addresses of a domain (for example, email addresses misspelled by the sender) to a specified inbox.
• This ensures that messages are not lost and can be checked later.

Example:

Existing email box: test1@hostico.net
Incorrectly typed email box: tst@hostico.net
Automatically generated email box by robots: s87ybyu90u@hostico.net

• The common part is the correctly written domain: hostico.net.
• The messages will be received by the server and, according to the Catchall filter, will be redirected to a designated mailbox, for example: catchall@hostico.net.
• The sender will not receive error notifications, and spam robots will continue to send messages that will be captured.

Requirements

• The ISPConfig panel login credentials, received via email upon VPS activation.

Steps to follow

• Log in to the ISPConfig panel using one of the following addresses:
  • https://SERVERNAME:10200
  • https://IP_SERVER:10200
  • https://DOMAIN.XX:10200
• After logging in, click on Email in the navigation bar.
• Select the green button Add new Catchall.

Setting up the Catchall filter

In the next window, fill in the fields as follows:

• Source: The domain for which the filter is created.
• Destination email: The email box where the messages will be redirected. This mailbox must be created in the Email Accounts -> Email Mailbox section.
• Allow destination to send from email addresses in this domain: Check to allow messages to be sent from the destination mailbox.
• Enable Greylisting: Check to pass messages through the Greylist filter, recommended for anti-spam protection.
• Active: Leave checked to enable the filter.
