Email encryption refers to encryption , and often authentication , of email messages, which can be done in order to protect the content from being read by unintended recipients. Technology for email is readily available see below , but has not achieved widespread adoption, apparently due to social factors, such as people seeing the use of encryption as paranoid, and as marking a message urgent whether it is or not Gaw et al, 2006 . Email encryption can rely on public key cryptography , in which users can each publish a public key that others can use to encrypt messages to them while keeping secret a Public key cryptography private key they can use to decrypt such messages or to digitally encrypt and sign messages they send. Encryption Protocols Popular communications protocol protocol s for email encryption include Pretty Good Privacy PGP S MIME Transport Layer Security TLS Identity based encryption Mail sessions encryption Mail sessions encryption The STARTTLS SMTP extension is a Transport Layer Security TLS SSL layer on top of the SMTP connection. While it protects traffic from being Packet sniffer sniffed during transmission, it is technically not encryption of emails because the content of messages is revealed to, and can be tampered with, by involved email relays. In other words, the encryption takes place between individual SMTP relays, not between the sender and the recipient. When both relays support STARTTLS, it may be used regardless of whether the email s contents are encrypted using another protocol. STARTTLS is also an extension of Internet Message Access Protocol IMAP4 and Post Office Protocol POP3 , see RFC 4616. References Shirley Gaw, Edward W. Felten, and Patricia Fernandez Kelly.

An email attachment is a computer file sent along with an Emailemail message . One or more files can be attached to any email message, and be sent along with it to the recipient. This is typically used as a simple method to share documents and images. A paper clip image is the standard image for an attachment in an email client . Current usage Size limits Email standards such as MIME don t specify any file size limits, but in practice email users will find that they can t send very large files. Over the Internet a message will often pass through several mail transfer agent s to reach the recipient. Each of these has to store the message before forwarding it on, and may therefore need to impose size limits. The result is that while large attachments may succeed internally within a company or organization, they are unreliable when sending across the Internet and for that reason sending systems often arbitrarily limit the size their users are allowed to submit. ref http exchangepedia.com blog 2007 09 exchange server 2007 setting message size.html Exchange Server 2007 Setting Message Size ... that you may not be able to send larger attachments to contacts who use other email services with smaller ... size , mail.google,com . ref .

An email storm is a sudden spike of Reply All messages on an email distribution list , usually caused by a controversial or misdirected message. Such storms start when multiple members of the distribution list reply to the entire list at the same time in response to the instigating message. Other members soon respond, usually adding vitriol to the discussion, asking to be removed from the list, or pleading for the cessation of messages. If enough members reply to these unwanted messages this triggers a chain reaction of email messages. The sheer load of traffic generated by these storms can render the Mail Transfer Agent email servers inoperative, similar to a Denial of service attack DDoS attack . Some computer virus email viruses also have the capacity to create email storms, by sending copies of themselves to an infected user s contacts, including distribution lists, infecting the contacts in turn. Incidents On October 14, 1997, a Microsoft employee noticed that they were on an as yet unknown email distribution list Bedlam DL3 , and emailed the list asking to be removed. This list contained approximately a quarter of the company s employees, 13,000 email addresses. Other users replied to the list with similar requests and still others responded with pleas to stop replying to the list.

An email box also email mailbox , e mailbox is the equivalent of a letter box for email electronic mail . It is the destination where electronic mail messages are delivered. Definitions A mailbox is identified by an email address . However, not all email addresses correspond to a storage facility. The term pseudo mailbox is sometimes used to refer to an address that does not correspond to a definitive mail store. Email forwarding may be applied to reach end recipients from such addresses. Electronic mailing list s and email alias es are typical examples. RFC 5321 ref RFC 5321, Simple Mail Transfer Protocol , J. Klensin, The Internet Society October 2008 , Section 2.3.11 Mailbox and Address ref , defines an email address as a character string that identifies a user to whom mail will be sent or a location into which mail will be deposited.

Notability date July 2009 Email injection is a security vulnerability that can occur in Internet application software applications that are used to send email messages. It is the email equivalent of HTTP Header Injection . Like SQL injection attacks, this vulnerability is one of a general class of vulnerabilities that occur when one programming language is embedded within another. When a form is added to a World Wide Web Web page that submits data to a Web application, a malicious user may exploit the MIME format to append additional information to the message being sent, such as a new list of recipients or a completely different message body. Because the MIME format uses a carriage return to delimit the information in a message, and only the raw message determines its eventual destination, adding carriage returns to submitted form data can allow a simple guestbook to be used to send thousands of messages at once. A malicious spam electronic spammer could use this tactic to send large numbers of messages anonymously. More information on this topic, including examples and ways to avoid the vulnerability, can be found at the http www.damonkohler.com 2008 12 email injection.html SecurePHP Wiki .

Email jamming is the use of sensitive words in email s to jamming jam the authorities that listen in on them by providing a form of a Red herring plot device red herring and an intentional annoyance. It is used by some civil rights activism activists in an attempt to thwart government spy networks such as ECHELON . Activists deliberately include sensitive words and phrases in otherwise innocuous emails to ensure that these are picked up by the monitoring systems. The theory is that the senders of these emails will eventually be added to a harmless list and their emails no longer intercepted, thus allowing them to regain some privacy .

The term Mail Hub is used to denote an Message transfer agent MTA message transfer agent or system of MTAs used to route email but not act as a mail server having no end user email store since there is no Mail User Agent MUA mail user agent access. Examples could include dedicated anti SPAM appliances, anti virus engines running on dedicated hardware, email gateways and so forth. DNS Based Mail Hub A first example for a Mail Hub consisting of a network of MTAs would be that of a typical small to medium size Internet service provider ISP , or for a FOSS corporate mail system. This solution is very good for developing nation ISPs and NGOs. As well as any other low budget but high availability mail system needs. This is mostly due to not using expensive Network level switch es and hardware.
