It is highly recommended to protect any MailStore Gateway with appropriate firewall rules. This document should help with setting up the required rules.
Please note: On Windows, the installation process automatically creates an appropriate firewall rule. Therefore the below information is only applicable if other firewall solutions are used.
If the computer on which MailStore Gateway has been installed is on a private network, refer to the manual of the route or firewall that connects the private network to the Internet in order to find out how to set up appropriate port forwarding rules in addition to the firewall rules described in this document.
The table below lists all TCP ports that need to be opened in the firewall when using MailStore Gateway. The following abbreviations are used in the source and target columns of that table:
- ANY = Any computer from private or public networks
- ADM = Computer or network used for administration
- SERVER = Server that hosts MailStore Gateway
| Port | Source | Target | Description |
