IMAP protocol checking

The Internet Message Access Protocol (IMAP) is another Internet protocol for e-mail 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 the message has been read, replied to, or deleted. ESET Cyber Security Pro provides protection for this protocol, regardless of the email client.

The protection module providing this control is automatically initiated at the system startup and is then active in memory. Make sure that IMAP protocol checking is enabled for the module to work correctl.  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 separated by a comma.

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