There is a case where a stock standard Debian install of exim (and possibly postfix) can turn out to be an open relay. What happens is the the satellite email server blindly forwards email to the smart-host, and the smart-host blindly trusts the satellite system because it's within the trusted domain. Between the two of them they become an open relay. -- Donovan Baarda [EMAIL PROTECTED] http://minkirri.apana.org.au/~abo/
closing exims open relay - something to do with the percent hack
Hi, I just did an open relay test on one of my servers and to my surprise found that it in an open relay. In particular, it accepts emails to the form of [EMAIL PROTECTED] where here.com is a local domain within exim. I have tried setting percent_hack_domains= but that has not helped. I have also tried adding the line no_relay_match_host_or_sender as recommended in the docs but I dont actually know what it doesn. Any help in resolving this appreciated.
