Here is information for my VPS
NethServer release 7.5.1804 (final)
My Question is, if I buy NethServer Subscription “Crostino Good Starter” the issues fixed ?
Other question if I would like add more three domains for mail server, the Nethserver support multi domain ?
Why when I try to add email account the system not allow choose @domain ?
