    I have a working configuration of ISPConfig 3.0.16 with mail server and website/virtual domain handling.

    All my domains are FQDN and the server send and received mails using webmail as well as IMAP/SMTP mail clients.

    My users have reported that their email is detected as spam to many of their recipients.

    The question is: How to make my server legit and known as NOT spam for every spam detection engine/website out there?

    Do I have to complete any kind of forms or subscribe to a specific organisation?

    Please help

    Thanks

    No.

    1) Make sure that your server is run on a static IP address.
    2) Check if your server is blacklisted: http://www.mxtoolbox.com/
    3) Create SPF Records for your domains in DNS.
    4) Make sure that the IP address of your server has a correct reverse dns record.

    A general purpose one is

    Record Type: TXT
    Domain: example.com.
    Data: v=spf1 a mx -all
    Priority: 0

    added "a" : A records specify senders (without this some services, like yahoo, will automatically put you in spam).
