mail-notification SSL/TLS

This text explains a simple workaround for mail-notification in Debian/Ubuntu distributions, where the package has been built without SSL-support. In the web, you can find two workarounds: The first is a documentaion, where you are told to recompile the package with the missing libssl-support.

The second is trying to work with unmodified packages. This has the advantage that you won´t lose changes, when you are upgrading your distribution to a newer version.

Simply install stunnel4 with

aptitude install stunnel4

and put a configuration like this into /etc/stunnel4/:
===== Begin ; stunnel configuration file


  ; Some security enhancements for UNIX systems - comment them

  ; out on Win32

  chroot = /var/run/stunnel4/

  setuid = stunnel4

  setgid = stunnel4

  ; PID is created inside chroot jail

  pid = /stunnel4.pid
  ; Some performance tunings

  socket = l:TCP_NODELAY=1

  socket = r:TCP_NODELAY=1

  compression = rle
  ; Workaround for Eudora bug

  ;options = DONT_INSERT_EMPTY_FRAGMENTS
  ; Some debugging stuff useful for troubleshooting

  ;debug = 7

  ;output = /var/log/stunnel4/stunnel.log
  ; Use it for client mode

  client = yes
  ; Service-level configuration
  [imaps1]

  accept = localhost:1143

  connect = mail.roessner.it-zahner.de:993
  [imaps2]

  accept  = localhost:1144

  connect = some.other.imap.server:993

; vim:ft=dosini ===== End

Then enable stunnel4 in /etc/default/stunnel4 and start it with
/etc/init.d/stunnel4 start

After doing this, you may configure mail-notification. Put localhost and ports
1143, …, into your connection fields.

Inside General:
Server: localhost

Inside Connection:
Standard Port 1143

This is working for me 😉
