Blocked domain

[rellik]

Hi all
I think our domain has been blocked from sending mail. When I send mail (setting outgoing mail server to smtp.saix.net) i get the following:

Your message did not reach some or all of the intended recipients.

Subject: test
Sent: 12/07/2005 08:37 AM

The following recipient(s) could not be reached:

'Recipient' on 12/07/2005 08:37 AM
554 Service unavailable; Sender address [[email protected]] blocked using rhsbl.saix.net; RHSBL03 See http://www.saix.net/accept.html

How do i unblock it?

Time to start emailing people at SAIX I guess? [email protected], [email protected], and [email protected] are where I would start.
Would you mind pm'ing me your email address, I want to test something with it quick as well.

Check your mail server that it is not an open relay. SAIX actively scans the adsl ip ranges for servers with port 25 open, and attempts to relay a message through that server, if it is successful it blacklists that ip, and prevents relay through smtp.saix net.

Check your logs:
