Even in this age of private and public organizations merrily handing out their email Gmail or some other “cloud” provider, there still are lots of organizations that run their own email server. This is better, in my opinion, for reasons I have already explained in “Wanted: Virtual Personal Email Servers”. Every now and then, however, the administrator of one of those servers goes online and asks something like “how can I automatically refuse or delete all email coming from certain countries?
- Infostrada is one of the biggest Internet Access Providers (IAP) in Italy. Barracuda is a software filter that analyzes all the email messages entering the network of an organization in order to block spam, viruses and similar. Whenever an Infostrada customer (but it may happen with other IAPs too, keep reading!) sends an email message to somebody “protected” (possibly without knowing it, because the filter is installed by an administrator) by Barracuda, something can happen that may create actual problems both to the sender and to the receiver.
