Introduction to Email
Introduction to Email gcflearnfree.org/print/email101/introduction-to-email Introduction Do you ever feel like the only person who doesn't use email? You don't have to feel left out. If you're just getting started, you'll see that with a little bit of practice, email is easy to understand and use. In this lesson, you will learn what email is, how it compares to traditional mail, and how email addresses are written. We'll also discuss various types of email providers and the features and tools they include with an email account. Getting to know email Email (electronic mail) is a way to send and receive messages across the Internet. It's similar to traditional mail, but it also has some key differences. To get a better idea of what email is all about, take a look at the infographic below and consider how you might benefit from its use. Email advantages Productivity tools: Email is usually packaged with a calendar, address book, instant messaging, and more for convenience and productivity. Access to web services: If you want to sign up for an account like Facebook or order products from services like Amazon, you will need an email address so you can be safely identified and contacted. Easy mail management: Email service providers have tools that allow you to file, label, prioritize, find, group, and filter your emails for easy management. You can even easily control spam, or junk email. Privacy: Your email is delivered to your own personal and private account with a password required to access and view emails. -

Characters in the Local Part of a Mail Address RFC2821 and RFC2822 State Clearly That Only 7Bit ASCII Characters Are Allowed in Internet Mail Addresses
Characters in the local part of a mail address RFC2821 and RFC2822 state clearly that only 7bit ASCII characters are allowed in Internet mail addresses. The following list shows all the ASCII characters and explains whether they can or should be allowed in the local part of a mail address. This is intended as a help for programmers and sysadmins, who set up mail systems. Source: http://www.remote.org/jochen/mail/info/chars.html Dec Hex Char Usable? Description 0-31 0x00-0 Control NO Not allowed by RFC2822. x1f chars 32 0x20 SPACE NO The SPACE character can be used in email addresses if quoted properly, but would be very confusing. Don©t use it. 33 0x21 ! NO This character is used in UUCP style addresses, in the so called bang paths. Example: host2 ! host1 ! user. Because there are still lots of mail systems who interpret this chars specially it should never be used in the local part of an email address. 34 0x22 " NO The double quotes are used for quoting. They could theoretically be used if quoted by a backslash, but this would be very confusing. Don©t use them. 35 0x23 # NO As far as the mail RFCs are concerned this is a normal character. But the hash sign is used in many configuration files to denote the beginning of a comment. Used in the configuration of most MTAs it would probably not work. Don©t use it. 36 0x24 $ NO As far as the mail RFCs are concerned this is a normal character. Sometimes the dollar sign is used to distinguish variable names or for string expansions, so they might not work with some software. -

How to Add an Email Address to Your Safe Senders' List
How to Add an Email Address to your Safe Senders' List An increasing number of e-mail clients (Outlook, AOL, Hotmail, etc.) are including spam blockers that can affect delivery and display of some e-mail messages. This means that sometimes those desired e-mail communications might not reach you, or they might be displayed without images. To ensure that you continue receiving your e-mail or your subscriptions, and that they display properly, we recommend adding the email address or domain to your list of safe senders. Here are some instructions to help you do that: Instructions regarding email clients Apple Mail • Add the email address to your address book. • In Training mode, emails will arrive in the INBOX highlighted in brown. In Automatic mode, junk emails will arrive in the Junk box. To add an email that arrived in the JUNK folder, highlight the email message. • Choose Message > Mark > As Not Junk Mail AOL For AOL version 9.0: You can ensure that valued e-mail is delivered to your Inbox by adding the sending address to your "People I Know" list. • Open your latest issue of Brill’s E-Newsletter. • Click the Add Address button (over on the right) to add that sender to your "People IKnow" list. Alternatively, you can simply send an e-mail to [email protected]. Even if the e-mail you send doesn't get through (for whatever reason), the act of sending it does the job of putting the address into your "People I Know" list--and that's what counts. -

M3AAWG Best Practices for Unicode Abuse Prevention February 2016
Messaging, Malware and Mobile Anti-Abuse Working Group M3AAWG Best Practices for Unicode Abuse Prevention February 2016 Executive Summary For years, visually confusable Unicode characters – e.g., using the Greek omicron (‘ο’ U+03BF) in place of a Latin ‘o’ – have provided the potential to mislead users. Because most functional elements, like links and addresses, were previously limited to ASCII, abuse remained peripheral. However, the scope and definition of this abuse are poised to change with the advent of International Domain Names (IDNs), Internationalized Top-Level Domains (TLDs), and Email Address Internationalization as these non-ASCII and non-Latin characters gain in popularity. This document outlines M3AAWG best practices to curtail the Unicode abuse potential of such spoofing, while supporting the legitimate use cases. The intended audiences for these practices are: email service providers, Internet service providers, and the operators of Software as a Service or others in relations to other Internet-connected applications. A brief tutorial explaining how Unicode characters are used to perpetuate abuse can be found in M3AAWG Unicode Abuse Overview and Tutorial paper. This paper can be downloaded from the Best Practices section of the M3AAWG website. I. Background The M3AAWG best practices approach is to disallow certain characters not in common usage, as well as the combining of confusable scripts within a single label, with exceptions made only for certain visually distinct combinations found in legitimate usage. The intent of this exacting strategy is to inhibit suspicious combinations from taking hold by legitimate users, while ensuring a clean delineation of what constitutes abuse. For consistency and defensibility, these strategies are based on the Unicode Consortium’s standardized “Restriction Levels” definition1, which takes into account expected legitimate combinations of character sets. -

Standard Unicode 4.0. Wybrane Pojęcia I Terminy
Janusz S. Bień Standard Unicode 4.0. Wybrane pojęcia i terminy 24 listopada 2005 r. Streszczenie Ukazanie się w sierpniu 2003 r. czwartej wersji standardu UNICODE (1504 strony plus CD-ROM), dostępnego także pod adresem http://www.unicode. org, stanowi okazję do zaprezentowania wybranych aspektów tego standardu. Unicode jest ukazany na tle wcześniej stosowanych metod kodowania tekstów. Artykuł zawiera również w sposób mniej lub bardziej jawny propozycje tłuma- czenie używanych w standardzie angielskich terminów na język polski. 1. Wprowadzenie Na wstępie warto przypomnieć różnicę między standardem a normą. Stan- dardy — dawniej pisane i czytane standarty1, ang. standards — to specyfikacje sformułowane przez pewne organizacje lub instytucje. Normy — ang. legal standards — to specyfikacje sformułowane przez krajowe lub międzynarodowe organizacje normalizacyjne, czyli przez instytucje upoważnione do tego przez państwo odpowiednimi ustawami; niektóre aspekty normalizacji krajowej i eu- ropejskiej omówiłem w artykule [2]. W skali światowej działalność normaliza- cyjna jest podstawowym źródłem utrzymania znaczącej liczby osób, stąd często można spotkać normy, których jedyną racją bytu jest dostarczanie zajęcia nor- malizatorom; standardy znacznie częściej zaspokajają rzeczywiste potrzeby ich użytkowników. W artykule [1] przedstawiłem krajowe, europejskie i międzynarodowe normy określające kodowanie tekstów polskich w systemach komputerowych. Tutaj podam tylko kilka przykładów kodowania polskich liter zgodnie z najnowszymi polskimi normami. Według -
