Hi, i previously posted about a "bug" that i was not able to correctly describe/identify, but now i got it.
I don't know why, but in my Samsung Tab 2 10.1, aqua mail client update messages only when i slide down the messages list.
If i click on the circular arrow icons on the right of the mailbox name, new messages are correctly fetched, but already fetched messages (eg. by other clients such as thunderbird with IMAP on the same email account) are not shown on the messages list.
