8 ``Mail transfer agent'' is a term covering a variety of programs. One thing is common to them: they transport email from one \emph{thing} to another. These \emph{things} can be hosts, meaning independent machines, or protocols like \NAME{SMTP} and \NAME{UUCP}, between which mail is transfered.\footnote{\sendmail{}'s initial purpose was moving mail between \NAME{UUCP}, \name{Berknet} and \NAME{SMTP}.} 8 ``Mail transfer agent'' is a term covering a variety of programs.

10 Beside this common property, \MTA{}s can be very different. Some of them have \NAME{POP3} and/or \NAME{IMAP} servers included. Some can fetch mails through these protocols. Others have have every feature you can think of. And maybe there are some that do nothing else, but transporting email. 10 Beside this common property, \MTA{}s can be very different.

13 The candidates for the competition in the next chapter are a subset of the \MTA{}s available. Comparision between totally different programs (apart of one function) makes not much sense. One would not use a program for a job it is not suited for. Therefor \mta{}s that are rarely similar to \masqmail\ are not regarded. 14 The candidates for the competition in the next chapter are a subset of the \MTA{}s available.

15 The first group of programs to sort out are the so called \name{groupware} programs. These provide a whole lot of functions, including mail transfer, file storage, calendars, resource management, instant messaging and more. %FIXME: check 16 The first group of programs to sort out are the so called \name{groupware} programs.

22 Third, only \emph{sendmail-compatible} \MTA{}s will be regarded in the competition. The ones not \emph{sendmail-compatible} are not from big interest on \unix\ systems. %FIXME: write it the other way round: the group sorted out. 23 Third, only \emph{sendmail-compatible} \MTA{}s will be regarded in the competition.

26 The programs remaining are \emph{sendmail-compatible} ``smart'' \MTA{}s that do not offer masses of features unrelated to mail transport. 29 The programs remaining are \emph{sendmail-compatible} ``smart'' \MTA{}s that do not offer masses of features unrelated to mail transport.

28 For the comparision, five programs of this group are taken. These are: \sendmail, \name{qmail}, \name{postfix}, \name{exim} and \masqmail. The four alternatives to \masqmail\ are the most important representatives of the regarded group. 31 For the comparision, five programs of this group are taken.

42 The \masqmail\ program was written by Oliver Kurth, starting in 1999. His aim was to create a \mta\ which is especially focused on computers with dial-up connections to the internet. \masqmail\ handles situations which are rarely solveable with the common \MTA{}s. 52 The \masqmail\ program was written by Oliver Kurth, starting in 1999.
