Secure your business with Email Hosting
They cater mostly to demanding e-mail users and Small and Mid Size (SME) businesses, while larger enterprises usually run their own e-mail hosting service. E-mail hosting providers allow for premium e-mail services along with custom configurations and large number of accounts. In addition, hosting providers manage user’s own domain name, including any e-mail authentication scheme that the domain owner wishes to enforce in order to convey the meaning that using a specific domain name identifies and qualifies e-mail senders. An e-mail hosting service is an Internet hosting service that runs e-mail servers. E-mail hosting services usually offer premium e-mail at a cost as opposed to advertising supported free e-mail or free webmail. E-mail hosting services thus differ from typical end-user e-mail providers such as webmail sites.
Almost all webhosting providers offer standard plans that include space, numbers of inbox accounts and etc. E-mail authentication is the effort to equip messages of the e-mail transport system with enough verifiable information, so that recipients can recognize the nature of each incoming message automatically. It differs from content filtering. Most e-mail hosting providers offer advanced premium e-mail solutions hosted on dedicated custom e-mail platforms. The technology and offerings of different e-mail hosting providers can therefore vary with different needs. E-mail offered by most webhosting companies is usually more basic standardized POP3 based e-mail and webmail based on open source webmail applications like Horde or SquirrelMail.
It provided for no formal verification of sender. Signing e-mails is a good first step towards identifying the origin of the message, but it does not establish whether that identity has a good reputation or whether it should be trusted. Ensuring a valid identity on an e-mail has become a vital step in stopping spam (as e-mail can be filtered based on such an identity), forgery, fraud, and even more serious crimes. The Simple Mail Transfer Protocol (SMTP) is continuously evolving, but when it was designed, in the early 1980s, it was the purview of academia and government agencies, and as such, there was no cause to consider security.
Thus, it is quite easy for a spammer to make an exact copy of an e-mail from example.com, including a long complicated sequence of headers and a genuine logo in the body of an e-mail, then change the content to send readers to a website that appears to be genuine, but is actually a phishing scam designed to capture names, passwords, and credit card numbers. An e-mail features four key players: the authors or originators of the e-mail, the sender or agent who first puts the e-mail on the public Internet, the receiver or agent who receives the e-mail from the Internet, and the recipients who are the persons intended to read the e-mail. Thanks to the Transmission Control Protocol and to IP address registries the sender’s IP address is automatically verified by the receiver. However, there is no provision for the verification of the author and sender information that is eventually saved in the relevant headers.
Service providers can block this type of email using IP address reputation technology. IP address reputation is a technology that monitors emails based on their source IP address. The technology tracks the email for spam activity and blocks messages from that sender once spam activity begins. IP addresses within the headers thus cannot be used to identify the source of a forged email. In addition to forged headers being used to throw off identification attempts, it is not uncommon for the legitimate headers within the email to reference a system insulated from the forger; the sender may, for example, be a zombie that has been compromised by a Trojan horse.
