The Intra2net system comes with a powerful mailing list management system. In addition to user groups, you can set up mailing lists under "Services > Email > Mailinglists".

In addition to internal users and groups, external email addresses can also be added. If the Intra2net system does not manage a domain via multidrop or SMTP, there is the problem that the distribution list does not have an externally accessible email address. To solve this, you can set up a POP3 account under "Services > Email > Polling", from which emails for the mailing list are collected. At the same time, the email address entered under "External Mailing List Address" is also included as a reply address in all emails to external members.
