IMAP protocol checking

The Internet Message Access Protocol (IMAP) is another Internet protocol for email retrieval. IMAP has some advantages over POP3. For example, multiple clients can simultaneously connect to the same mailbox and maintain message state information such as whether a message has been read, replied to, or deleted. ESET Endpoint Security for macOS provides protection for this protocol, regardless of the email client.

The protection module providing this control is automatically initiated at system startup and is then active in memory. Make sure that IMAP protocol checking is enabled for the module to work correctly. IMAP protocol control is performed automatically with no need to reconfigure your email client. By default, all communication on port 143 is scanned, but you can add other communication ports if necessary. Port numbers must be delimited by a comma.

If you select Enable IMAP protocol checking, all IMAP traffic is monitored for malicious software.
