How to set a Proxy

There is already proxy support available for the PEE client, however I didn't find the time to add a GUI element for this feature. Until this feature has been added, edit the settings file manually. You'll find it in your home directory on:
.yakkamail/state.xml

It contains a number of individual settings for your client, like size, position, etc.:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns3:guistate>        
 <mainBounds>
    ...        
  <toolbarDirectionEditor>North</toolbarDirectionEditor>
</ns3:guistate>

Edit this file and add right before the last line your proxy data, like in the example below:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns3:guistate>
    <mainBounds>
       ...
    <toolbarDirectionEditor>North</toolbarDirectionEditor>
    <proxySettings>
         <httpHost>yourproxyhost.com</httpHost>
         <httpPort>8080</httpPort>
         <httpsHost>yoursslproxyhost.com</httpsHost>
         <httpsPort>8181</httpsPort>    
    </proxySettings>

</ns3:guistate>
