Email Bounce

March 19, 2014 - By 

An e-mail bounce is simply when an electronic mail does not successfully reach the intended recipient. The email bounces back to the sender with an error message indicating that transmission was unsuccessful.

There are two types of bounces: hard bounce and soft bounce. A hard bounce occurs when the recipient’s mail server rejects the email. Once an email is dispatched, the system searches for the recipient’s domain and mail server. The recipient’s mail server will then use its programmed instruction to determine if the email can pass through. If, for example, the recipient has blocked the sender’s address, the server will reject the message and bounce it back. The server may also bounce the message if it cannot process the incoming mail for some reason, for example if it’s too busy processing other requests.

Soft bounces occur when an email is received and accepted by the recipient’s mail server, but for some reason, the message cannot be delivered to their mailbox. Once the message is received and accepted by the recipient’s mail server, the system determines if the address actually exists on the server. If the system can’t find the address due to, for example, a misspelled address, the message is bounced back. A soft bounce can also happen if their mailbox is not currently able to receive messages at the time because of low disc space, or the size of the received message exceeds the maximum size the mailbox can receive.

An email inbox is a folder in which all incoming messages are received and stored by default. This applies to webmail interfaces or desktop email clients like Outlook. Storage-wise, there are two types of inboxes. You can use a POP3 account on an email client in which case the emails can be retrieved and stored on the hard drive, or you can use an Internet Message Access Protocol (IMAP) mail server in which case your inbox will be on the mail server.

Having the messages on your hard drive has the advantage of accessing old emails even without an internet connection. On the other hand, you need an active connection to access even your old mail on an IMAP mail server.

The inbox is only meant to be a receiving and sorting folder and keeping all your messages in it is misuse. If you receive a lot of business and casual mail, it becomes difficult to wade through the swamp of unread relevant and irrelevant mail. For this reason, it is prudent to have separate folders for business, friends’ and family emails. Upon reading a message, push it into its designated folder. Failure to do this may result in what is called ’email bankruptcy’, where you decide to delete all mail regardless of the sender just so you can start afresh.

Multipurpose Internet Mail Extensions (MIME) is an internet standard which extends the format of an email to support the text in character sets, the non text attachments, message bodies with several parts, the header information to be presented in non ASCII characters. Basically MIME was designed for SMTP protocol, but today its use has grown beyond the limits of simply describing the content of an email.

Now it often includes describing the content in general as well, including the content for web, and also acts as a storage source for rich content in certain commercial products. MIME defines several new mechanisms for sending various types of information in the email like, text in other languages except for simple english using the character encodings.

The content kinds defined by MIME standards stand of great importance outside an email, as in communication protocols like HTTP for World Wide Web.
