 Hi,
 specially when my notebook is connected via wireless network e.g. umts it
 can happen that my network connection gets lost without a signoff from the
 XMPP server.

 In that case it can happen that somebody sends me a message an I'll never
 get it, because usual XMPP doesn't includes that the clients acknowledges
 message receptions. So until my clients reconnects to the server or the
 connection to the server times out all messages will be lost.

 To handle this, there is the "XEP-0079" extension for XMPP.
 http://xmpp.org/extensions/xep-0079.html

 Can you please implement this in Pidgin/libpurple? Currently the Tigase
 XMPP server and maybe some more servers provide this feature.

 support-tigase
 https://projects.tigase.org/projects/tigase-server/files

 Tigase also has an own server running their Tigase server software.

 Please do not consider this as just an enhancement. In some way it's a bug
 in the XMPP protocol and it leads to very unforeseeable behavior.

 Additionally it would be nice if Pidgin tells me if my server currently
 supports the feature.

 Thanks!
