No. It does simple TCP connects, doesn't know about IMAP at all and won't send any string, it just checks if the TCP port is available. Would it be a problem to remove the log message altogether, at least for trusted IPs or make it a warning, not an error. What is so bad with TCP connects/disconnects without any IMAP traffic, especially when they originate from trusted IPs?
