Hello,
For a long time I fail to establish an IMAP connection with Gmail. A POP connection works fine, but IMAP doesn’t. I enabled IMAP in the Gmail settings.

The strange thing is also, that I don’t receive any error messages in EmClient. Below you see my latest log, but nothing appears in my inbox folder:

What to do? Can someone help me out?
