I wrote a Perl script to analyse the logs and calculate traffic both moved on the network and moved on our mail server.

If folks go above a threshhold they are sent email indicating this and asking them to either check their mail less often or to remove their mail from the server when they check it, or both. The mail then goes on to explain that if they do not do this, they will be billed for the excess. An estimate of the bill amount is included.

I have only had one user ignore this. This person was popping mail every minute and leaving about 40 megs of mail on the server. We sent him a bill for about $900. He freaked. We pointed out the earlier email that he had ignore He calmed down and appologized and started to negotiate. We reversed the bill. It is not our intention to actually bill for this, but we don't want to get into an argument with our customers about what is appropriate for them. We just set prices.

Seems to work - none of our customers are currently abusing the system.

Dear All
I have a number of users you are checking for mail very frequently, every
30s etc.
besides asking them not to is there any way other way to stop them.

I feel that every 5 minutes is more than enough.
This constant check really produces a lot of unnecessary traffic.

This has only became a problem since ADSL (DSL) has became available in
Spain.

Have other people experienced this situation.
