ISPConfig 3 mail server SPAM question
 
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.

You can use this wizard to get an idea how your SPF record should look: http://old.openspf.org/wizard.html

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).
