Have good passwords
Remember: Passwords are the only lock and key tools on the internet.
Protect your password:[1]
Use more than 7 characters in your password.
User more than 7 characters in your password
Choose from these characters
` ~ ! @ # $ % ^ & ; * ( ) = + - _ ; :
/ ? ' " | [ ] { } <>
They are who they say they are
Tips for choosing a password:
The above topic may seem as trivial or repetition, however understand that password is the only lock and key system.

VIII. Understanding The Need For Message Signatures The first reason for message signatures is authenticity. It is a largely unknown fact that the From: header of email can be trivially forged. A quick glance can lead you to believe that the mail was sent by someone who might not have had anything to do with the message. A signature will help you determine if the mail was really sent by who you think it was sent by. The second reason for signatures is integrity. Someone who has access to any piece of mail that is waiting for you (perhaps at your ISP) can change the message. This could affect something as simple as where you should meet someone to something as serious as which bank account you should transfer money to. A signature can tell you if the message was modified between the sender and your mail client.This document
will explain the need for signing and how to sign messages, how to
verify signatures on mail sent to you, how to encrypt messages, and how
to decrypt messages. Theft of your private key by anyone means theft of your identity. In anincreasingly digital world, your private key will soon carry as muchweight as a photo ID, and in some situations already carries more.

email-risks-5
email fatigue, email bankruptcy, Flaming
Most business workers today spend from one to two hours of their
working day on email: reading, ordering, sorting, ‘re-contextualizing’
fragmented information, and writing e-mail.
The use of e-mail is increasing due to increasing levels of
globalization—labour division and outsourcing amongst other things.
E-mail can lead to some well-known problems:
email worms problem is most common today on the more popular Microsoft Windows operating system
is much easier and faster to understand than unedited and sometimes
unrelated fragments of information. Communicating in context can only
be achieved when both parties have a full understanding of the context
and issue in question.
for those who are nervous or poor articulators in face to face
situations. This can lead to society becoming less personal with a
greater number of people being unable to hold conversations face to
face.
Flaming occurs when one person sends an angry and/or antagonistic
message. Flaming is assumed to be more common today because of the ease
and impersonality of e-mail communications: confrontations in person or
via telephone require direct interaction, where social norms encourage
civility, whereas typing a message to another person is an indirect
interaction, so civility may be forgotten. Flaming is generally looked
down upon by internet communities as it is considered rude and
non-productive.
Also known as "email fatigue", e-mail bankruptcy is when a user
ignores a large number of e-mail messages after falling behind in
reading and answering them. The reason for falling behind is often due
to information overload and a general sense there is so much
information that it is not possible to read it all. As a solution,
people occasionally send a boilerplate message explaining that the
email inbox is being cleared out. Stanford University law professor Lawrence Lessig is credited with coining this term, but he may only have popularized it.[22]
be a problem when a large team is working on documents and information
while not in constant contact with the other members of their team.
he usefulness of e-mail is being threatened by four phenomena: e-mail bombardment, spamming, phishing, and e-mail worms.
E-mail worms use e-mail as a way of replicating themselves into vulnerable computers. Although the first e-mail worm affected UNIX computers,
the problem is most common today on the more popular Microsoft Windows operating system
reaching their destination, meaning it is relatively easy for others to
intercept and read messages;
messages on their mail servers before they are delivered. The backups
of these can remain up to several months on their server, even if you
delete them in your mailbox;
Despite these disadvantages, email has become the most widely used medium of communication within the business world.

E-mail privacy, without some security precautions, can be compromised because:
reaching their destination, meaning it is relatively easy for others to
intercept and read messages;
messages on their mail servers before they are delivered. The backups
of these can remain up to several months on their server, even if you
delete them in your mailbox;
There are cryptography applications that can serve as a remedy to one or more of the above. For example, Virtual Private Networks or the Tor anonymity network can be used to encrypt traffic from the user machine to a safer network while GPG, PGP, or S/MIME can be used for end-to-end message encryption, and SMTP STARTTLS or SMTP over Transport Layer Security/Secure Sockets Layer can be used to encrypt communications for a single mail hop between the SMTP client and the SMTP server.
Additionally, many mail user agents do not protect logins and passwords, making them easy to intercept by an attacker. Encrypted authentication schemes such as SASL prevent this.
Finally, attached files share many of the same hazards as those found in peer-to-peer filesharing. Attached files may contain trojans or viruses.
