Hello Carsten, thank you for your feedback. You are right, it was an SSL/TLS issue. I have checked the error console in icedove and saw a message relating to "weak ephemeral diffie-hellman keys". So I contacted the owner of the server and suggested what to do. Even if they claimed they have not touched anything, it suddenly began to work. So it works now but I don't know why ... :/

This smells a little bit like there are issues with TLS/SSL. Did you mentions the infos from README.Debian within /usr/share/doc/icedove/? Otherwise note please note https://wiki.debian.org/Icedove#Debugging_Icedove_Activity and look there for issues. > When I start Icedove from CLI I can see (this is also the stuff logs are > filled with): > > kuda@d8-30042015:~$ icedove > > (process:4068): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_ size == 0' failed > Gtk-Message: Failed to load module "canberra-gtk-module" This doesn't matter here, unfortunately this warning is some kind of normal. > I am running 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u3 (2015-08- 04) x86_64 GNU/Linux, > the system is up to date (21.08.2015). > > I am sorry for making noise if this is something that can be easily fixed. Such errors could all been solved in the past so no need for excusing. Regards Carsten"
