All mails from my server go to spam

[evicon]

Hi guys,
here is all working fine.... all but not this thing.
My server has 10 sites, I manage all with ispconfig and I don't have problems the only annoying thing is, all my client's mail sent out via webmail or pop client (outlook) go to spam folder when received.
I've been added to some blacklist too. I suppose it's 'cos in the headers of mails I've incompatible data:

You will need to create a SPF record for: mydomain.org
Add the SPF record to the DNS that you use for: mydomain.org

well I'd like but I really dunno how, btw I don't think it's the problem or better this doesn't depend from it by all.
I suppose the problem is I'm sendig out mail from a account in a domain and this header is
Received: from xxx-xxx-xxx-xxx.vps.virtuo.it (xxx-xxx-xxx-xxx.vps.virtuo.it [xxx.xxx.xxx.xxx])

where xxx-xxx-xxx-xxx.vps.virtuo.it is not the name of the domain I'm sendng from but the dns record to find the server.

or I'm totally wrong?

The Received: from xxx-xxx-xxx-xxx.vps.virtuo.it (xxx-xxx-xxx-xxx.vps.virtuo.it [xxx.xxx.xxx.xxx]) is the revers DNS. You will need to ask your provider to set this for you.

However this is (I think) not the main problem!
(Hotmail does need a correct revers DNS, but Gmail does not)

It's hard for us to see if your SPF is set correct, as you are maskin everything with xxxxxxxx

Are you using the DNS from the registrar (the place where you got the domain from), or are you using an ISPconfig created DNS?

If it's the DNS from the registrar, you will need to add the SPF at that DNS!
If it's the DNS from ISPconfg, you will need to set it in ISPconfig!

You could also try http://www.dnsreport.com/tools/dnsreport.ch?domain=your_domain_name, and see if it's giving a pass for a SPF record found.
