Title: Somewhat OT, Spam and Bandwidth

70-80 Users can create a lot of traffic. Much more then a 256 kBit line can handle. Depends on what customers are doing. Are this all users working 8 hours a day on the computer or does some/all of them browsing and mailing only sometimes?   As Christopher said MRTG would be very usefull here. It's also possible to create IMail usage stats with MRTG. (google for "imrtg")   Do you have the possibility to block smtp traffic (stop imail smtp service) for - let's say - 10 minutes? Sending MTA's should requeue incomming messages and you can see what happens with your slow line.   Markus     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Christopher Checca Sent: Thursday, December 02, 2004 3:54 PM To: [EMAIL PROTECTED] Subject: RE: [IMail Forum] Somewhat OT, Spam and Bandwidth YES, IMO anyone that has more an 50 users needs a full T1 to supply internet access and email.  In my system we currently have 73 in house and 138 remote sites (with between 170 and 200 people), that needs access to our services (email, citrix, internet, web site, intranet, etc.) and we have an N*T1 (3MB) pipe.  During business hours we run at about 50% cap on avg.  I would setup MRTG to monitor your router or firewall to get a better look at what’s happening.  http://people.ee.ethz.ch/~oetiker/webtools/mrtg/   This tool is a real life saver!   To see a sample of what it looks like you can look at my personal web server … http://www.checca.net/mrtg/       Christopher Checca Packard Transport, Inc.
