From Wikipedia, the free encyclopedia

An email hosting service is an Internet hosting service that operates email servers.

Email hosting services usually offer premium email at a cost as opposed to advertisement-
supported free email or free webmail. Email hosting services thus differ from typical end-
user email providers such as webmail sites. They cater mostly to demanding email users
and Small and Mid Size (SME) businesses, while larger enterprises usually run their own
email hosting service on their own equipment using software such as Sendmail or Postfix.
Hosting providers can manage a user's own domain name, including any email
authentication scheme that the domain owner wishes to enforce in order to convey the
meaning that using a specific domain name identifies and qualifies email senders.

Most email hosting providers offer advanced premium email solutions hosted on dedicated
custom email platforms. The technology and offerings of different email hosting providers
can therefore vary with different needs. Email offered by most webhosting companies is
usually more basic standardized POP3 based email and webmail based on open source
webmail applications like Horde, RoundCube or SquirrelMail. Almost all webhosting
providers offer standard email hosting.
