We did never send out spam but our emails often end in spamfilter.
So I went to: http://www.dnsreport.com/tools/dnsreport.ch?domain=psxtune.com
(there are other domains with other problems on the server but that is the most important one)

And get

WARNING: One or more of your mailservers is claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). If your mailserver sends out E-mail using this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam software. This is also a technical violation of RFC821 4.3 (and RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should have an A record pointing back to the same server. Note that this one test may use a cached DNS record.

psxtune.com claims to be non-existent host nohavename.cr:
220 nohavename.cr ESMTP Exim 4.50 Tue, 03 Apr 2007 20:00:38 +0200

when I change the hostname to psxtune.com than I get rid of that problem but get on all other domains that it does not match and I get some emailproblems on other domains.

Is it somehow possible that every hosted domain is answering with the right hostname?:confused:
Getting blocked or ending in the spam box is really bad for us
 
For email to work you need a hostname. You need a working IP# for that hostname, and you need working reverse DNS for that IP#. The reverse DNS doesn't even have to resolve to the hostname, but it probably should.

That's all you need.

If after doing that you still get warnings from DNSReport, that's okay.

Your server isn't going to be able to call itself something different every time it connects, and you can't have more than one rDNS setting anyway, so any server that will call you a spammer because of this is misconfigured and marking as spam almost all the email that comes from almost all webhosting servers.

Note, though, that a host name should always be in the format hostname.example.com, not example.com.

thanks that makes things a lot clearer!
That page also recommends SPF (Sender Policy Framework), does that make sense in your personal opinion? directadmin.com homepage seems to have it.
 
DA includes a default SPF record for every DNS zone it creates.

The reason it is not there is because your nameservers are
Code: 
NS1.WORLDNIC.com
NS2.WORLDNIC.com
so you need to set up the SPF records at worldnic.com where the domains pointing to. If you had custom nameservers setup with the domains pointing to them, it would be read because it would be reading the records from your server instead of the worldnic.com servers.

The idea of the Worldnic nameservers was to be more flexible in case of server change. Now it seems to be a disadvantage. Do you know if it is possible at networksolutions (that is where the worldnic servers are) to set up the SPF?
 
There should be, look under the domain management area for advanced DNS settings, or something like that. See if there is a spot to add your own records for the domain and add the SPF record to it. You can look at what the SPF record should be under the DNS Administration area of DA for that domain, just pretty much copy paste it from there for the DNS record at worldnic.com (as long as you are hosting your email from that server, if not, replace the IP with whatever your email server is).
