Len You recently recommended an Oreilly book that was awesome for sh commands and scripting. I'd like to get it for christmas, could you please repeat the title for me? Thanks -A

The problem is that they send from their own server, but their MX is at postini, so SAV contacts postini but postini MX is too stupid to verify its paying clients as "known users". So senders or ip's need to be whitelisted. Here's a couple of commands to check for them: #find sending PTR's when "psmtp" PTR is failing SAV: grep -i "smtpd.*reject.*psmtp" /var/log/maillog | awk '{print $10}' | sort -f | uniq -ic | sort -f #find [EMAIL PROTECTED] "psmtp" PTR is failing SAV: grep -i "smtpd.*reject.*psmtp" /var/log/maillog | cut -d ";" -f 2 | awk '{print $1}' | sort -f | uniq -ic | sort -f Len
