47 There is a third type of \mta{}s in between the minimalistic \name{relay-only} \MTA{}s and the feature loaded \name{groupware}. Those programs may be named ``real \MTA{}s'', or ``proper \MTA{}s'', though there is no common name. They are what is meant with the term ``\mta''---programs that transfer mail between hosts. 47 There is a third type of \mta{}s in between the minimalistic \name{relay-only} \MTA{}s and the feature loaded \name{groupware}.

49 Common to them is their focus on transferring email, while being able to act as \name{smart host}. Their variety ranges from ones mostly restricted to mail transfer (e.g.\ \qmail) to others having interfaces for adding further mail processing modules (e.g.\ \postfix). This group covers everything in between the other two groups. 49 Common to them is their focus on transferring email, while being able to act as \name{smart host}s.

106 \sendmail\ is the best known \mta, since it was one of the first and surely the one that made \MTA{}s popular. It also was shipped as default \MTA{}s by many vendors of \unix\ systems. %fixme: ref 106 \sendmail\ is the best known \mta, since it was one of the first and surely the one that made \MTA{}s popular.

108 The program was written by Eric \person{Allman} as the successor of his program \name{delivermail}. \person{Allman} was not the only one working on the program. Other people developed own versions of it and a variety of flavors came up, especially in the late eighties when Allman was inactive. %fixme: ref 108 The program was written by Eric \person{Allman} as the successor of his program \name{delivermail}. \person{Allman} was not the only one working on the program.
