Here's the plugin I wanted to develop: <http://www.pan-am.ca/dmp/dmpstats.zip>
It's a simplistic thing so if you decide to use it, pay attention to your server to make sure the dmpstats program doesn't hang or crash. It should otherwise always return "none" for the mfilter error code, so it always passes mail. I haven't set up any DMP records in the domain dmp.pan-am.ca yet, so for the first little while I just need a log sampling over 24 hours. This will let me determine the more popular domains your recipients deal with, along with their host names and outgoing server IP addresses, so I can create test records. Once I've set up some DMP records for those domains in dmp.pan-am.ca, I'll ask you to run the plugin again for seven days and send me the log file. I might ask sppecific folks to run it again for a while, as I try to determine what mind of impact DMP has. Here is the kind of impact I expect: * A DMP lookup takes about half a second before any caching, including network delays. Incoming mail will slow down by about that much until your server's DNS resolver cache builds up. Antirelay3 had a similar effect so it'll be about the same as it is for Antirelay. * Traffic over port 53 will increase. You will be causing a traffic hit on my DNS server for every e-mail you receive. If you query live DMP records, which isn't recommended yet, you will cause a similar hit on each sender domain's DNS servers. If, for the first part, you want to specify your own DNS server as the target, you'll be saving me some grief. You can also specify your own DNS domain to base lookups on, to start. * A log file will grow where you specify it to. This has about the same impact as the mailspool inlog, probably a little less. Actually, when I build up my DMP test zone, I'll make copies of it to all of the volunteers so you can add it to your own servers if you want. This way you're not impacting my DNS server. Also regarding building up a DMP test zone, if you happen to know a domain's outgoing mail server IPs, do tell me about them.
