It's just spam. You should have been easily rejecting such crud: 10 dnsbls are listing that IP address as a spam source: http://www.mxtoolbox.com/SuperTool.aspx?action=blacklist%3a195.191.72.102 You are apparently not using any dnsbls in your Postfix config (or the wrong ones). At minimum you should be using Spamhaus ZEN. It is free of charge unless you routinely do over 300,000 lookups a day. It might be beneficial for you to send your postconf -n output so we can make some anti spam configuration suggestions. This spam you're having a problem with would likely not have made it past the normal spam filters of most people on this list. -- Stan
