    The SEL has two official domains:

    • selroc.systems - Second domain of the SEL, officially dedicated to the forum.

    Unofficial domains of the SEL:
    • portx.org - unofficial placeholder page.
    • arteltelematica.net - historical domain.

    The selroc.systems domain has an SPF Record. An SPF record is a Sender Policy Framework record. It is used to indicate to mail exchanges which hosts are authorized to send mail for a domain. It is defined in RFC 4408, and clarified by RFC 7208.

    The record is implemented in the DNS Server.

        Apparently the https://www.selroc.systems site is not accessible from Germany, this is not intentional in any way, and maybe the fault of some TOR network user who got blocked by the firewall.
