Does anyone have any contact information for roadrunner netops? Its unfortunate that their local offices won't escalate you to the proper party in times of need. Its also unfortunate that their "offices are closed". /micah

BMITU

This is my first post so please be gentle. I would like to get some opinions on the Best Mailserver in the Universe. Is there a more appropriate list for this question? I have looked at Communigate Pro, IMAIL, and others. I am interested in integrated solution that can scale to handle 500k accounts Any experience good / bad would be great. Thanks /SF

We have tested all of them. We process several million messages per day for tellurian.com. The only server which doesn't die immediately or within 30-60 minutes is Surgemail. All others are crippled by multi-threaded and multi-homed dictionary attacks very quickly. I am speaking only of Win32 servers.

Spam assassin could not handle the load and choked on the mail volume. We were only able to process 1-2 messages per second with spam assassin. (not running spamc/spamd since it doesn't work on Win32) We can now peak at 50-100 messages per second without any problem. The ruleset is completely customizable and it includes a distributed razor-like checksuming spamtrap database. Even without Bayes capability, with thousands of messages per day, I only receive one or two false positves or false negatives per week. > In particular, I'd also like to see effectiveness benchmarks, > such as the ones recently reported at > <http://freshmeat.net/articles/view/964/>.

Unfortunately, spam assassin is so effective and popular that spammers are using the rules to game SA now. We use a different ruleset than SA so we are less susceptible to forced false negatives. >> It includes support for AVAST >> anti-virus > > Any other anti-virus solutions supported?

ethernet-based temperature sensors
by matthew zeier 04 Sep '03

I know this has been mentioned before, but other than NetBotz (too pricey), what are people use as ethernet-based, SNMP-probable temp sensors? I very simply need to trend temp with cricket/mrtg in various parts of the data center. Looking for real-world experience. Thanks. -- matthew zeier - "Curiosity is a willing, a proud, an eager confession of ignorance." - Leonard Rubenstein

>that nothing can equal, much less beat, sendmail. This is especially >true when you start talking about filtering for spam or viruses via >the milter interface. What are people using for network based anti-virus? A friend of mine started a company www.raeinterent.com/rav and claims to have an industrial anti-virus app that plugs into Communigate Pro. Any experience with network based anti-virus & mail systems? Thx

I second the vote for Postfix. I haven't used it with a ton of users, but I built a large mail cluster for my old employer which was used to send stock pricing alerts to users that have set up thresholds for certain stocks. Initially, the cluster was qmail (that was back in 2000). I used qmail because it's performance was better than anything else I tested, including postfix. Qmail is a pain to administer, especially when you have a bunch of them. After getting fed up with qmail, I tested Postfix again, and the newer versions of it outperformed qmail by a longshot, and I could spawn many more connections with it without running out of file descriptors. Adding features to qmail sucks because it's always a patch, and it's usually something that most other mailservers already have built in. When you install it and have 10 patches that you need to apply, you need to apply them in the right order so they don't step on each other. There are some limits in qmail that you need to patch for in order to make it work in a very large environment, like the big-concurrency patch and the patch to increase the size of the queue. Administration of postfix can all be done with the postconf command, you don't have to edit config files at all. This makes it great for clusters because I had a script I wrote that would execute a command across all of the machines in the cluster. So a config change for every machine involved typing: grun 'postconf -e whatever = something' grun 'postfix reload' I've heard some good things about exim, but in my testing, I was unable to get the performance I could get with postfix. Maybe it was my fault, I didn't spend that much time with Exim because the ease of administration with Postfix was vastly better than any other mailserver I've used. Postfix rocks. Apple just ripped sendmail out of OS X and replaced it with Postfix if that says anything. -jay > -----Original Message----- > From: Jack Bates [mailto:jbates@brightok.net] > Sent: Thursday, September 04, 2003 10:32 AM > To: Fisher, Shawn > Cc: Nanog List (E-mail) > Subject: Re: BMITU > > > > Fisher, Shawn wrote: > > > I would like to get some opinions on the Best Mailserver in > the Universe. > > Is there a more appropriate list for this question? > > I'm partial to sendmail due to the grandfather clause, but if > I could go > back in time and redesign everything, I'd be a diehard postfix fan.

I bodged up something using one of these and a DS9097U RS-232 adaptor: http://www.neil.nu/temp.html I realise this is probably only of peripheral interest, as the original post requested a unit with SNMP capability, and the DS1820 doesn't provide anything as sophisticated. It was, however, completely free of charge as I got the bits as samples from Farnell in the UK. The software to drive the units is freely available, and it should be pretty trivial to get it to mail a pager or whatever if the temperature goes outside of limits.
