I have changed ISPs and one of my IPs is on the DSBL blacklist (since 2004). In the removal instructions there is this... "All you need to do is teach your mail server software to treat "127-0-0-1.dsl.your-isp.net" as an inbound domain equivalent to "your-domain.com" for which it should accept mail." I can't find anything in any postfix documentation that clearly tells how to do this. Any ideas please?
