Title: Somewhat OT, Spam and Bandwidth

Glenn,

 

I have a Folder containing 45.000 Spam messages (45k IMail D.SMD and 45k IMail Q.SMD files)

All files has a total size of 250 MBytes. So any message (Message + Queue file) has an average size of 2,78 kBytes.

 

Assuming that the queue file has a similar size as protocol overhead has durring transmission over your  T1 line and multiplying this average size with your daily 2856 spams the result is around 8 MB of data created by spam messages. This is not very much compared to one single 5 Megapixel picture send from a friend to one of your users.

 

A 256 kBit Line should be able to handle 8 MBytes in 32 - 40 seconds.

 

Markus

Subject: [IMail Forum] Somewhat OT, Spam and Bandwidth

We have 70-80 users here.  For our net connection, we're running a fractional T1, 256K.  In terms of what comes in and out of the building, we have email, of course.  Users are allowed to surf the Internet.  We have a few tiny services that run that are allowed from the outside, such as a website and a Citrix box. 

In trying to download files, service patches, whatever, I noticed that our downloads are all pretty slow.  The obvious answer is to get more bandwidth.  But I did a spam count recently to check to see how much we're getting.  In a day and a half we captured 2,856 spam items, and that's just the spam that was caught.  I'm sure there was some that wasn't caught.  I know we're getting much more spam then legitimate emails with the low number of users we have.  I don't know much about how email is delivered, how long it takes, etc.  But can all this spam really be hurting our net connection?
