It is highly recommended to protect any MailStore Service Provider Edition service with appropriate firewall rules. This document should help with setting up the required rules. The firewall rules for running the SPE in Single Server Mode can be found in this article.

Important Notices:

  • The communication channels described below MUST NOT be intercepted by any kind of email or web proxies that are provided as part of antivirus software or unified threat management gateways.

The below table lists all TCP ports that need to be opened in the firewall when using MailStore Service Provider Edition in multi server mode. The following abbreviations are used in the source and target columns:

  • ANY = Any computer from private or public networks
  • ADM = Computer or network used for administration
  • CAS = Server hosting Client Access Server role
  • IH = Server hosting Instance Host role
  • MGMT = Server hosting Management Server role
