This is about in-game mail in the EVE Portal app.
I use the app EVE Portal and added my character to it a few weeks ago. Everything was working fine.
Last friday I quit a corporation but in the activities list in the EVE Portal app (the ‘FEEDS’ window) I still see mails that are send by corp leaders to the whole corp… (the corporation that I left). I cannot read the body of the mail, but I can read the subject of them. This gives me infomation that I should not be able to read.
I talked to GM BigBear about this and he said to file a bug report. In the meantime, please be careful about what information you put in the subject of your in-game mails.
