implementar nuevo plugin!

Hello,

I implemented a new plugin for exodus that shows an alert window when the
user has received a new mail in the inbox.

I would like to save the e-mail server configuration in the branding.xml
file and then take the information in the branding.xml file from my
plugin.

I have been reading the information in the exodus web page but I couldn't
find anything about this.

Anyone could tell me how can i do that?

Thanks in advance!
