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 or not the message has been read, replied to or deleted. ESET Cyber Security Pro provides protection for this protocol, regardless of the email client used.

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 other communication ports can be added if necessary. Port numbers must be delimited by a comma.

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