Re: [WISPA] Re-evaluating our anti-spam solution
I know of Barracudas that the only time they get rebooted is for firmware updates. They can run for months without a reboot, but usually the firmware updates have useful stuff in 3-6 months that requires a firmware upgrade. John Charles Wyble wrote: > David E.

Currently we are looking to replace out Barracuda due to ongoing issues with the box that after several attempts to work with Barracuda can not be resolved. Barracuda is helpful but like to point at other things like DNS and unrelated stuff. In the end they log into the box after wasting time so something to kick the box and we are good for an undetermined amount of time. The Barracuda gives us a few features that we like such as an in house box that we are not paying per email address or domain. Also the per user configurability is great for letting users independently control their white and blacklists. In a nutshell what products should we look at that offer us similar features as the Barracuda box. You can roll your own with Postfix and a few addons. After looking at the configuration options for a lot of the Postfix addons, you come to the realization that with a few hours of work, you can have all of the software tools used by the Barracuda internally, and have root access to the box to fix it yourself when it goes south, instead of waiting on them. You can also throw in things like redundant hard drives, and redundant power. How a company can market a $3k+ device with a single IDE drive in good conscience is beyond me.

One should NEVER have to reboot a mail server, outside of a kernel upgrade (and even then one can use ksplice). I'm sorry but that's a pathetic resolution process. I have mail/web/dns servers with years of uptime. They sit there and just work. RAID + UPS = 100% uptime. WISPA Wants You!

Re: [WISPA] Re-evaluating our anti-spam solution
Block people from using those sites? Kick them off your network? Are these end users doing this? Or do they have bot infected machines using webmail to send spam in an automated fashion? If so then snort+clamav should do the trick. I presume folks run inbound and outbound IDS right? I sure hope so. :) Olufemi Adalemo wrote: > I have rather different anti-spam requirements > For a while now I've been looking for a solution to stop users on a network > sending spam via web-based email like Hotmail, Gmail and Yahoo by scanning > the outgoing HTTP POST command on a proxy server based on Bayesian > statistics like Dansguardian which would have been great if it did POST > scanning, is there anything new out there that fits this description? > > Femi > > > From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On > Behalf Of Travis Johnson > Sent: 14 July 2009 05:40 > To: sarn...@info-ed.com; WISPA General List > Subject: Re: [WISPA] Re-evaluating our anti-spam solution > > The difference with Postini compared to an in-house box is Postini stops the > incoming SPAM before it uses any bandwidth on our backbone.

+1 for postfix and the mentioned add ons. 3k and it's not redundant? Good grief. Though it's not a few hours. https://help.ubuntu.com/community/Postfix Copy/paste from the howtos.

I've had them get overwhelmed with mail, and the solutions was to wait for their support to connect in and "clear the logs". I could have done that myself! What pushed me over the edge, was a failed hard drive. I was running a Spam Firewall 300, which yes, I know, is not a RAIDed config. (which is another rabbit hole to go down, considering the box is $3k+) and the hard drive started to throw errors. The problem, was that these errors were not evident to us as the admins of the machine. None of the Barracuda logs indicated any sort of issue. The box got slower and slower, until one day, it refused to pass mail. When tech support took a look, they exclaimed that the hard drive had been throwing errors for quite some time, any now it was too late, the box was dead. Their solution always worked very well, and I didn't need to think about it. Until it blew up without telling anyone it planned to. WISPA Wants You!

Re: [WISPA] Re-evaluating our anti-spam solution
We're using Roaring Penguin Can-it Pro. Love it. Does everything and then some. The guys know their stuff.. They wrote the MIMEDefang program - http://www.roaringpenguin.com/products/mimedefang - (open source) that most anti-spam products use now, as well as the rp-pppoe client for linux. We moved to that from Postini. Randy Jason Hensley wrote: > Not cheap at all, but ModusMail does an outstanding job for us.

Re: [WISPA] Re-evaluating our anti-spam solution
I've been a huge fan of Postfix combined with Maia Mailguard (maiamailguard.com I think). Allows users to modify their own settings, white lists, blacklists, see little graphs on blocked spam for their specific account in addition to allowing them to help train the system by going through copies of their messages and verifying them as spam or non-spam.

Re: [WISPA] Re-evaluating our anti-spam solution
Agreed! Been using Postfix since I told Postini to take a hike. They both use a modified version of Postfix and related add-ons. You can make a spam machine out of the cheapest hardware now. I have been doing this for over 3 years and have a much better customer satisfaction.

Re: [WISPA] Re-evaluating our anti-spam solution
I use a something called ASSP, which is Anti-Spam SMTP Proxy. Not foolproof, completely, but highly configurable, the system learns from the spam reports sent to it reasonably well, and cuts our spam down by at least 95-98%. Oh, and it's free. I run it on spare hardware I had lying around. Doesn't seem to be CPU intensive, and not all that hard to get working. I actually have my email hosted elsewhere (outsourcd) but by using firewall rules and DNS entries, all incoming and most outgoing mail runs through it. - Original Message - From: "Jeremy Parr" To: "WISPA General List" Sent: Monday, July 13, 2009 5:28 PM Subject: Re: [WISPA] Re-evaluating our anti-spam solution > 2009/7/13 Jeremy Parr : >> 2009/7/13 Don Grossman : >>> It seems time to take a look at our anti-spam solution.

You can roll your own with Postfix and a few addons. After looking at the configuration options for a lot of the Postfix addons, you come to the realization that with a few hours of work, you can have all of the software tools used by the Barracuda internally, and have root access to the box to fix it yourself when it goes south, instead of waiting on them. You can also throw in things like redundant hard drives, and redundant power. How a company can market a $3k+ device with a single IDE drive in good conscience is beyond me. I can't find the link right now, but there is a package that provides users with an accessible, configurable quarantine, just like the Barracuda. I'll post the link as soon as it turns up.

[WISPA] Re-evaluating our anti-spam solution
It seems time to take a look at our anti-spam solution. Currently we are looking to replace out Barracuda due to ongoing issues with the box that after several attempts to work with Barracuda can not be resolved. Barracuda is helpful but like to point at other things like DNS and unrelated stuff. In the end they log into the box after wasting time so something to kick the box and we are good for an undetermined amount of time. The Barracuda gives us a few features that we like such as an in house box that we are not paying per email address or domain. Also the per user configurability is great for letting users independently control their white and blacklists. In a nutshell what products should we look at that offer us similar features as the Barracuda box. Thanks Don WISPA Wants You!
