RE: SPAM blockin software recommendations..... [bcc]
Not to be too redundant here, but I have been running Postfix on a Slackware box as a corporate SMTP gateway. I would highly recommend Postfix for such an application. The benefits of such a system are RBL checks on incoming mail, low overhead, and with rrd one can produce pretty little graphs(to show management). Recently Spam had become a major problem for us, as many others I am sure. I decided to implement SpamAssasin with Postfix in advanced filtering mode. There is plenty of documentation on different filtering techniques with Postfix. Since 2/12/03 SpamAssassin has caught 10143 pieces of UCE with a very low false positive rate. The best part about the system is it costs our company $0. Just some thoughts on non commercial software.

RE: SPAM blockin software recommendations.....
Well, setting it up now (again after a play install this morning). I don't wish to turn this into a Postfix list so if anyone can help and would care to answer off-list: At present my box is on the LAN, if I've called it relay.mira.co.uk and I want it to accept any mail for the mira.co.uk domain and forward it to otherserver.mira.co.uk do I use virtual domains or, as I think, transport mappings? Reason I ask is that the transport mappings don't appear to work if I use the format domain.com smtp:[otherserver.mira.co.uk] regards, Paul -- Paul Hutchings Network Administrator, MIRA Ltd.

We use the www.tummy.com server distro of Redhat. Strips out the GUI which we don't need and don't want, and gives us an updated server CD once a month.

RE: SPAM blockin software recommendations.....
I would say it depends on the company, as my last place we had 15 Exch Admins just for the UK, god know how many more in the US Europe, Asia. Each of different levels and responsibilities for different areas of Exchange (backup, external, interconnection with notes, basic admin, security/encryption, hardware/OS), so I would have thought it depends on the site structure if they would need to know.

RE: SPAM blockin software recommendations.....
I guess we're kind of lucky. Our ISP filters all our mail before delivering it to our Exchange server AND he doesn't charge us for it (makes sense if you think about it - he's saving bandwidth as much as we are). I don't know of all the rules he uses but there are two: reverse DNS lookup and checking the HELO greeting against the RFC. If the mail fails either one it never comes across the wire to his server. Needless to say we have a number of irate parents who complain that they can't get mail through but in EVERY case it was a misconfigured email server on their end. For those who absolutely MUST get mail through, I have a separate school account set up with the ISP on a non-spam basis, configured so that Outlook will check it every 5 minutes. So the end-user gets an email alert when new mail comes into that account. They really don't know that the account exists so they can't use it to register for free stuff on the web. Some crap still gets through, but iHateSpam does a pretty good job of stopping the few pieces that do.

RE: SPAM blockin software recommendations.....
I have issues with anyone blocking my mail for me unless I have access to that blocked mail. Too many chances for a false positive. As an example, we forced reverse lookups on our mail server once. That is until we figured out our most important client could no longer email us. Now we cant very well tell them sorry, your mail server is messed up.

RE: SPAM blockin software recommendations.....
I'd disagree with both your assessment of sendmail. It took about an hour to configure 4 OpenBSD systems to route mail for about 12 domains, and include both whitelist and blacklist entries for addresses and servers. Its also easy to set to run in a protected shell environment. Qmail isn't all that much easier to configure. Either way, if you don't understand DNS, and I mean REALLY understand DNS with respect to mail flow, neither will work correctly. -- Roger D.

Sendmail isn't easy to setup, or administrator. We ran Sendmail for years out in the DMZ, so I speak from much experience. If you must run Sendmail, then I recommend the commercially supported Sendmail Switch, which will run on Windows 2000, and is available from http://www.sendmail.com/products/msmgr_routing.shtml. It comes with a web interface, and for someone who isn't Unix experienced, is at least, doable. My biggest issue with Sendmail is that is a HUGE security risk - it has a new massive security hole about once every six months. Due to the nature of its design - one size fits all - and that it runs damn near everything as root, I would say it is impossible to every be truly secure. Last week, for example, a new hole was discovered and received world-wide publicity: a buffer overflow, which was accessible simply by sending a specially constructed email with a malformed TO, CC, or BCC line to a non-patched Sendmail server. When exploited, it gave root control of the Sendmail server to the attacker. I recommend qmail, which is not only highly secure - it has NEVER had a security breach - but is also at least 4-5 times as fast as Sendmail, and much, much easier to set up and configure.

RE: SPAM blockin software recommendations.....
Sendmail isn't easy to setup, or administrator. We ran Sendmail for years out in the DMZ, so I speak from much experience. If you must run Sendmail, then I recommend the commercially supported Sendmail Switch, which will run on Windows 2000, and is available from http://www.sendmail.com/products/msmgr_routing.shtml. It comes with a web interface, and for someone who isn't Unix experienced, is at least, doable. My biggest issue with Sendmail is that is a HUGE security risk - it has a new massive security hole about once every six months. Due to the nature of its design - one size fits all - and that it runs damn near everything as root, I would say it is impossible to every be truly secure. Last week, for example, a new hole was discovered and received world-wide publicity: a buffer overflow, which was accessible simply by sending a specially constructed email with a malformed TO, CC, or BCC line to a non-patched Sendmail server. When exploited, it gave root control of the Sendmail server to the attacker. I recommend qmail, which is not only highly secure - it has NEVER had a security breach - but is also at least 4-5 times as fast as Sendmail, and much, much easier to set up and configure.

It comes with a web interface, and for someone who isn't Unix experienced, is at least, doable. I'm a admin for both Sendmail and Exchange, and not just 2 of each.. I don't think Sendmail is harder then Exchange, in fact I think it's easier. Hmmm but I do have Linux experience, on Linux I refuse to use anything that looks a GUI. Nothing beats vi or pico. My biggest issue with Sendmail is that is a HUGE security risk - it has a new massive security hole about once every six months. Due to the nature of its design - one size fits all - and that it runs damn near everything as root, I would say it is impossible to every be truly secure. Yeah, sure, but almost everything you say goes for Exchange too, security issues, need to patch frequently.. one size fits all.. Sendmail configuration is just compile and install it, install your own .cf (created from one file and added what you need). Sendmail security has improved much, right know only a part runs as root, the other as smmsp (an user with almost no privs at all). Last week, for example, a new hole was discovered and received world-wide publicity: a buffer overflow, which was accessible simply by sending a specially constructed email with a malformed TO, CC, or BCC line to a non-patched Sendmail server. When exploited, it gave root control of the Sendmail server to the attacker. I think an MS admin has other things to worry about right now. I think I remember there is a new code red.. I recommend qmail, which is not only highly secure - it has NEVER had a security breach - but is also at least 4-5 times as fast as Sendmail, and much, much easier to set up and configure. Now here we finally agree.. qmail has had no security issues at all (not that I'm aware of). You may want to think about Postfix too.. When it comes to security it doesn't really matter which OS you run. We need to patch both Windows and Linux. Everything I could think of in favor of one of them is left out. I don't intend to start a discussion about which OS is the best or the most secure. For everyone who do want to discuss this there are newsgroups like alt.computer.linux.advocacy and alt.computer.windows.advocacy or something like that.

I would recommend MX Logic's MX Spam Guard service. http://www.mxlogic.com In MX Logic lab tests the service catches 98.5% of spam with a false positive rate of 0.4% vs. Trend ScanMail eManager at 38% and false positve rate of 0.5%. Plus, administration of releasing quarantined false positives can be pushed to the users. The service starts at $0.75 per mailbox per month. I love ScanMail, but why pay for something like the eManager plug-in that doesn't work? Phil Isika -Original Message- From: Erik L.

I think you should check into TrendMicros' IMSS product if you're using Trend eManager. I think Messaglabs skyscan is one of the best service out there to catch spam, but it's costly and it catches too much until you customize it fit into your environment. I am implementing IMSS now, but I think it works, but not the best stuff out there.
