So I wanted a simple way to send email from my Ubuntu VM, and this is
the thing people generally use for this.

It was mostly a frustrating experience, so I would like to suggest some
ways to improve this package, and I am happy to help do this by sending
you patches etc..

- put /usr/bin/esmtp into /usr/sbin/esmtp instead, this is a system
  program like 'sendmail' so this makes more sense

- split package into 'esmtp' and 'esmtp-core' instead of 'esmtp' and
  'esmtp-run'. Two reasons for this, 1) this is the way packages are
  generally split these days and 2) a person should be able to just
  'apt-get install esmtp' and have a working mail system, most people
  are not aware that they need to install 'esmtp-run' instead. So
  'esmtp' would be 'esmtp-run' and 'esmtp-core' would be 'esmtp'.

- make the debconf high priority. On most default installs, no one sees
  the debconf, and since this package is useless without configuration
  it makes sense to make the debconf high priority

- smarter debconf config: we could make something like what thunderbird
  uses, where a person puts in their email address and password and it
  uses the Mozilla ISP database to figure out the SMTP server, port and
  settings.

Those are my ideas, let me know if you are interested and I will be
happy to implement them.

This is a very important package and the way most people set up email
when they do not need a complex MTA.
