Nel corso del mese di dicembre 2006 abbiamo provveduto ad installare un nuovo filtro per bloccare le email indesiderate (“spam”) e le email contenenti virus o files potenzialmente pericolosi per la sicurezza della nostra rete.
Le emails possono essere bloccate per le seguenti ragioni:

1. il server che ci invia posta per conto del mittente è stato incluso in una lista nera (black list) di server usati dagli spammers. In questo caso l’errore ritornato al mittente &egrave: “554 Rejected as spam x.x.x.x

In December 2006 we installed a new anti-spam/anti-virus email filter.
Emails can be blocked for the following reasons:

1. the sender’s email server has been included in a blacklist of known spammers. In this case the error returned to the server is “554 Rejected as spam x.x.x.x found in dnsbl.sorbs.net” or “554 Rejected as spam see: http://spamcop.net/bl.shtml?x.x.x.x” where “x.x.x.x” is the sender’s server IP address.
   This means that this server has been included in one of the two blacklists that I am using.

In 1999 I registered the domain digiampietro.com, switched my hosting company to WestHost.com and revamped my website. At the time dynamic content was not so popular and very few hosting companies supported dynamic content in their cheapest hosting offerings; Microsoft FrontPage was popular but I disliked it. After a bit of research I found a good solution in WML (Website Meta Language) an html scripting language that easily allowed the generation of a static web site with a consistent look & feel and navigation bar.… Read the rest

I published a personal web site for the first time in January 1996, subscribing, for a small fee for this service (no free hosting available at the time). The web site had few simple html pages, the most important page was my resume!. These pages had the following features:

• manually written html
• the background was grey as it was the common that days
• few kbytes of images to have nice and fast to download pages
• on the upper left of the home page I had a smiling picture of myself that was shot at the first birthday of my first daughter, on the top right another picture, scanned from a newsmagazine, with a tattoed arm with the motto Born to Network
• the home page started with the words “I’am a (relatively) young Electronic Engineer with almost ten years of experience …”.
