PFsense firewall with nethserver as mail server

[Gaetano_Battaglini (Petronio)]

I found this interesting and easy guide:

Howto make a simple mail server

Note This guide is fairly old. For a more complete and up-to-date guide, see the wiki at: https://wiki.nethserver.org/doku.php?id=email_protection_resources Target I would like to create a step by step howto for basic configuration of a public mail server. It might be useful for users who configure a mail server for first time then… I have an ADSL and Nethserver, how can I create a mail server? What do you need to start: Nethserver: ADSL with static IP. Any other soluti…

Two questions:
when Enzo Turri say: “Check your public ip”
How can I chek and know my public ip?

the guide if I undestand well is for SOGo groupware the step are the same for WebTop 5 groupware?

Thanks
