If you're with a company that doesn't have control over your own rDNS, you should NOT be sending mail out onto the internet IMO, the chances are your ISP provides a relay for you to do this. We've had very few issues with blocking outright on rDNS - blocked about 2.5 million connections yesterday alone, but we do provide meaningful error messages and provide people a method to report issues via our postmaster website. As a mail op for a large mail system, it is of my opinion that we can't let 'small companies' - who in my experience are FAR more likely to get compromised get away with poorly configured setups. If all of us larger operators start being stricter, we can pretty much solve the botnet generated spam -- Blog: http://pookey.co.uk/blog Follow me on twitter: http://twitter.com/ipchristian -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
