I'm in the need of installing the mail-server metapackage on my Ubuntu Server 15.10 machine.

I have installed the mail-server metapackage with the sudo tasksel command; but I'm not sure what to do next.

As a Google search shows, we have the official guide/intro from ubuntu.com here; this shows us:

  1. Mail Transfer Agent to send and receive emails
  2. Mail filtering to filter emails
  3. Mail Delivery Agent for IMAP/POP3 protocols support
  4. Webmail for web-interface-based email checking
  5. Mailing lists for mailing lists with email group

My question is which of the above 5 modules does the mail-server metapackage of tasksel install?

This is the full list of packages installed by sudo tasksel mail-server on Ubuntu 15.10 Desktop (I suppose the list may vary across releases):

% tasksel --task-packages mail-server | sort
bsd-mailx
dovecot-core
dovecot-imapd
dovecot-pop3d
libassuan0
libexttextcat-2.0-0
libexttextcat-data
libgpgme11
liblockfile1
liblockfile-bin
libpython2.7-minimal
libpython2.7-stdlib
libpython-stdlib
libtokyocabinet9
libwrap0
lockfile-progs
mutt
ntpdate
postfix
procmail
python
python2.7
python2.7-minimal
python-minimal
ssl-cert
tcpd

On Ubuntu 15.10 Server the following packages are missing from the above list:

libexttextcat-2.0-0
libexttextcat-data
liblockfile1
liblockfile-bin
lockfile-progs
ntpdate

So:

  1. postfix
  2. None of those. You'll have to pick an option and install additional packages.
  3. dovecot
  4. None of those. You'll have to pick an option and install additional packages.
  5. None of those. You'll have to pick an option and install additional packages.

    @NamGVU This is on Ubuntu 15.10 Desktop though, you may want to double-check that the list corresponds in Ubuntu 15.10 Server.
