i think my email account may have been hacked, I receive emails from my contact list but they are not sent from them
You email provider may offer you this functionality, but it’s not an information that eM Client (or any other email client) can access.
For example, in Gmail on the web the information is available on the Inbox page when scrolling all the way down and in the right corner there’s “Last account activity: X minute(s) ago”. Next to it there’s a “Details” button that shows recent accesses.
For other providers it may be available on the web, but the user interface will be different.
