Just wondering if anyone else is seeing what I've been seeing for the past few months. I have several customers running SA 2.63 on qmail.....for each of them I have setup an individual qmail server that scans their inbound email for spam and viruses. This box is setup in their MX records with a priority of 10. I have a fallback box that all of my customers utilize with an MX priority of 100.
I have been closely monitoring the Spam statistics using sa-stats.pl...what I'm seeing is that the dedicated boxes setup as the "primary" MX record is catching on average about 80% of all inbound emails. The "secondary" box (that is--the shared box with a priority of 100) is catching about 99.8% (if not 100%) on a daily basis. These are valid spams begin caught as well. This just seems odd to me that the secondary MX record would receive a much higher volume of spam and wondered of anyone else was seeing this and if there was an explanation. BTW, for the 3 or so customers I'm referring to, I process about 300,000 messages per day. The fallback box processes about 70,000 per day, with about 68,000 or more being caught as SPAM Thanks, Mike --- Outgoing mail is certified Virus Free.
