This is a list of mail servers: mail transfer agents, mail delivery agents, and other computer software which provide e-mail within Internet message handling services (MHS).

Product statistics[edit]

According to one survey, sendmail, Microsoft Exchange Server, Postfix, and Exim together control over 85% of market share for SMTP service in 2010.[1]

Another survey suggests a more balanced distribution, though it included hosted e-mail services such as Postini.[2]

These surveys are rather difficult to produce,[3] hence it is no surprise if they disagree.
