What we do not have time for this week, can be continued
on the next meeting.
W/o Rob't spotswood (sick), the Samba SIG didn't make much progress on
the mail server project. We did convince ourselves that KirraMail
doesn't install easily & isn't worth fighting w/ for having a 2nd mail
server on the network. We also discovered that the last release of
VMware 2.0 is useless. If we knew that either VBox or VMware would
save the complete state, including RAM, of a VM (this may be a
"stupid" question), then we could run Kirra in a VM, & have it have
We built a vmware KerraMail mail server just to see if we could set up a mail server. The samba SIG went well and I found thanks to Rick, some Google special searches under UNIX (google/linux, google/gov, and google/bsd) We learned that vmware doesn't do snapshots and virtual box does.
Today we got the spam script working and spammed our new server. Over a 100 MB
connection, it took about 14.5 minutes to send 10,000 messages. During that
time, CPU usage on the mail server shoot up to around 90%. However, even
during the storm, the webmail interface was still responsive. Nevertheless, it
showed that we need anti-spam measures.
In order to get the spam script running, we used another machine, then booted
with Knoppix 6.0.1 and installed sendmail (what the script requires). Knoppix
5.3.1 would not work with sendmail for some reason.
In the next meeting, we need to try to add some polish to our testing mail
server. The current list of items to address is:
1) Anti-spam measures and anti-virus measures. Current plans are to use
Amavis. It will be interesting to see what the load is on the server if we
repeat the spam storm with the measures in place.
2) Implement quotas. We can't have one user fill up the hard drive.
3) Change the squirrelmail url to something better and more standard, such as
4) Install a list manager. Mailman has been suggested.
It is likely it will take more than one meeting to accomplish all this.
Today work continued on the mailserver. Robert attempted to set up three interfaces to manage the users without resorting to raw sql statement and got two of them working. GRSoft MailManager is working and is a web based front end. Ispwebadmin we never got working. The final one is a bash script by manu that, although limited, works just fine. While this one won't be used much, it does leave open the possibility for a mass setup of email accounts with a little hacking of the script.We also got squirrelmail working too. Next up is one of two things, to be decided on in the coming two weeks:1) Set up a test network with some kirramail servers to test out the postfix mail server and make sure everything is working.2) Set up virus and spam filtering on the new mailserver. We've got a volunteer to be the evil spammer. He will try to counter our measures to block spam (on the test network). He will have the advantage on knowing what countermeasures we are using.
