Добро утро. Пусни един "honeypot" и може и да разбереш.

Type Mail is an app that helps you manage your email from your mobile device. When you add your Gmail, Yahoo, AOL, iCloud, Outlook.com, Exchange and other mail accounts, you authorize Type Mail to securely access your messages using an authentication method called OAuth in which your passwords are never stored on our servers. In some cases when OAuth is not used we access you account directly and securely. Our servers securely store a subset of your messages temporarily: this lets us give you the fastest possible access to important messages, like new or deferred emails. Of course, you retain any ownership and intellectual property rights you have in the content in your email (see the Copyright section of these Terms for more detail).


Попадал съм и на други андроид клиенти които теглят пощата не директно от имап на mail провайдера ами от сървър на компанията който тегли предварително и ги събира там. Може това да е случая.
