I just found some time to hack together a shell one-liner that should solve it for you (jn case your alert e-mail has a specific unique subject):
Code:
{ dbus-monitor & echo $! >dbusmonpid; } | { grep -q -m 1 'xxxSUBJECTxxx' && gst-launch-1.0 playbin uri=file:///home/nemo/Music/SOMEFILE.ogg.midi.wav.mp3 && kill $(cat dbusmonpid) && rm dbusmonpid; }
Replace the xxxSUBJECTxxx with any unique part of subject of your alert mail. And replace SOMEFILE with any music /sirene/noise sound file.
Tested and worked.



This is definitely not fool proof and could be extended with a loop and more. Oh and let the sound play to end (do not use ctrl-c), else the dbus-monitor process will not get killed.
About loudness I do not know with gst-launch but there should be some help.
So there is room for improvement. But hey it works!

Thanks @haltux for the right pointers!
