\secframe{about masqmail}



\frame{ \frametitle{what is masqmail}

a small mail transfer agent (MTA)

for non-permanent online connections

over multiple providers

written by Oliver Kurth between 1999-2003

}


\frame{ \frametitle{value of masqmail}

covers a niche

has unique features

has users!

}


\frame{ \frametitle{problems of masqmail}

no further development since 2003

unmaintained

emailing has changed

}










\secframe{short explanation of the thesis}



\frame{ \frametitle{ch01: introduction}

prerequisites

the masqmail project

value and problems of masqmail

\textbf{$\Rightarrow$ reasons for this thesis}

}



\frame{ \frametitle{ch02: market analysis}

classification, life cycle, and trends of electronic communication

SWOT and trends for email

\textbf{$\Rightarrow$ show that email will survive}

}


\frame{ \frametitle{ch03: mail transfer agents}

classification of MTAs

masqmail's competitors

short comparison

\textbf{$\Rightarrow$ provide knowledge for next chapters}

}




\frame{ \frametitle{ch04: masqmail's present and future}

the goal (revive masqmail)

requirements

fulfilled requirements

work to do

ways for further development

result

\textbf{$\Rightarrow$ the core of the thesis: how to revive masqmail}

}



\frame{ \frametitle{digression: the result}

``one fits all'' is not possible

hence: different strategies for different goals

short-term goal: keep masqmail usable\\
\quad$\rightarrow$ improve existing code

long-term goal: make masqmail future-proof\\
\quad$\rightarrow$ recreate it from scratch

disadvantage: more work

}


\frame{ \frametitle{ch05: improvement plans}

improvements of current code

a new design

\textbf{$\Rightarrow$ recommendations how to do the proposed changes}

}

\secframe{experiences}


\frame{ \frametitle{recommendations (to improve)}

use your time (lazy beginning)

focus early on structure

early and good literature search

keep a time buffer

}


\frame{ \frametitle{recommendations (what I did well)}

good backup (nightly!)

latex (know it already)

structure, structure, structure

never hesitate to throw stuff away

rework, rework, rework

}
