Problem:
if I send from Blackberry-Device (10) an email , there is first an error-message and after some minutes the email were sent 3 times !
Found this problem in user-threed 2014, but there was no practicable solutions.
I tried to include sogo-sources
deb http://inverse.ca/ubuntu trusty trusty, but this is not correct - Errors 404 for some packages.
Is there anyone, how knows a solution
Thanks for all tips .. .. ..
