e-mail rejected for spam

[surfweb82]

Hello.

I'm using ubuntu and rc7.

The problem is that many e-mail is rejected because it considered spam.
If I send e-mail from my gmail account that arrive, but if send from the other domains are rejected.

Why? How do I get all the mail?

Thanks for your help!

error:

Recipient address rejected: Mail appeared to be SPAM or forged. Ask your Mail/DNS-Administrator to correct HELO and DNS MX settings or to get removed from DNSBLs; MTA helo: swip.net, MTA hostname: mailfe15.tele2.it[212.247.155.205] (helo/hostname mismatch)

yeah because this domains mailserver is misconfigured...

you can add this mailserver to a whitelist (http://www.postfix.org/uce.html#smtpd_cl...trictions) or disable policyd-weight. (comment out check_policy_server inet:127.0.0.1:12525 in etc/main.cf...

When you really done that and mail does not arrive then there is another log entry...

I reboot server now and e-mail received... I disable reject_unknown_recipient_domain in main.cf and all work fine... for now..


I try again for a couple of days before closing this post!
