'm using openSuse 13.1 with Evo 3.10.4 and KDE only 4.11 and am also
using the Gnome keyring. I do not have this problem. I also have Gnome
installed and still do not see the problem UNLESS my mail server is
unreachable for whatever reason.
First, are you SURE your mail server is up and running correctly?
Have you tried with a different user? Have you tried removing Gnome
keyring and telling Evo to use the KDE password utility?
Do you want to contact me off list and I'll set up a temp email account
