Postfix reject connections

[falko]

As long as there are valid nameservers in /etc/resolv.conf the order of the nameservers doesn't matter much.

Do you have SPf records for your domains?
If you are sure you're not blacklisted, I'd contact Gmail and ask why your emails are blocked.

[gabrix]

SPf ???? Spam .... and than ? I got to the site you linked and tiped my domain name in the ip address box ... what ip can be blaklisted if dynamic ... ?

[gabrix]

I defenitly found out that gmail but also libero.it and a friend of mine who registred at my site didn't get password sent from my site on his hotmail.com account .I have sent few minutes ago some mails to mailing lists like the or-talk and bleeding-snort and i got mails from them they delivered mine .But this just after the last changes i gave to main.cf resolving (finger crossed!) the smtp_peer_init businnes i'm regulary receiving mail reports from logcheck on the gateway machine.
My question is , the directive relayhost = smtp.big.provider would sort this problem out ?How do i set it ?If i choose gmail shall i use the exact gmail smtp address (???) or would be all right a more generic smtp.gmail.com ?Or any other way ????

You know what ! I'm been running a mixmaster remailer for a little while recently , but i stopped it and removed it ... If i'm in a blacklist it's for this reason i supposed , cause wherever i send a mail it doesn't get delivered ,hotmail,ecn.org,virgilio,gmail ecc. It's really few where my mail does get through.That's really bad ! How can i get over this ?
I contacted the mtoolbox people and i'm waiting to see they can do ...

[gabrix]

I'm getting mail delivered but i don't know of much of it get removed . Looking at logs the score is not encouraging :

That's my actual main.cf:

biff = no
config_directory = /etc/postfix

relayhost =
smtpd_banner = $myhostname ESMTP $mail_name
smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, permit

[falko]

It must be

mynetworks = 192.168.1.0/24,192.168.0.0/24,127.0.0.0/8

Please change it and restart Postfix.

[gabrix]

Ok,done!What about the variable inet_interfaces shall i use the main eth0 ip 192.168.1.6 instead of ' all ' ?This way maybe the above change is going to be useless .... attached there is the last mail log.

[falko]

inet_interfaces = all

is ok.

What's in /etc/hosts?

If you are not blacklisted you should ask email.it why your server is blocked by them.

[gabrix]

/etc/hosts on the postfix machine (mail):

127.0.0.1 localhost.localdomain localhost
192.168.0.1 netgear router
192.168.0.2 argo.gabrix.ath.cx argo squid.gabrix.ath.cx
192.168.1.1 argo.gabrix.ath.cx gateway
192.168.1.2 makintoxik.gabrix.ath.cx makintoxik mac
192.168.1.4 www.gabrix.ath.cx tor.gabrix.ath.cx ftp.gabrix.ath.cx irc.gabrix.ath.cx jabber.gabrix.ath.cx w$
192.168.1.6 mail.gabrix.ath.cx printer.gabrix.ath.cx mail

What about email.it?It's an email provider !What could they do ?Maybe relay ?Actually i cannot send anywhere in the internet all my mail get bounced .
