meaningful energy consumption of KMail

[Sandro Knauß]

Hey,

kdepim-users is for users centered questions and discussions. To reach the 
developers there is a different malinglist is kde-pim. I forwarded your mail to 
this list now.

I find this determines a meaningful energy number of Kontact interesting. I 
think a good opportunity is to talk about it at Akademy [1] this month in 
Graz.

@joseph: Will this happen as part of kde eco / blue angle? Or is this 
unrelated?
