I use Kmail2 with DSL and PPP (56 ko Modem); I use networkmanager for DSL and Kppp for PPP. When I am connect with Kppp and NetworkManager enable, kmail refuse to receive or send mail (nothing append). With the previous NetworkManager plasmoid there was a button "disable" for turning off networkmanager and doing so made Kmail2 connecting to servers. Since Plasma-nm I need to switch from networkmanager to ifup (with yast2, as root, on Opensuse 13.1) for doing this. Would it be possible to change something in Kmail2 for solve this problem and autorize user to use kmails when connect with kppp thank you very much
if it's a NetworkManager bug it's not a kmail. Please open bug against it.
