Scanning of email messages downloaded from POP3/IMAP server

POP3/IMAP messages scanning is performed during message transfer between MAILBOX and MUA. All emails requested by POP3/IMAP clients are intercepted by the esets_pop3 (or esets_imap) agent module and scanned by the ESETS daemon for infiltrations. ESET Mail Security supports most common MUA programs, such as Microsoft Outlook, Evolution, Mozilla Thunderbird and others. Note that there is restriction in ESET Mail Security functionality when emails are downloaded by Mozilla Thunderbird using IMAP communication protocol. An email in this case is requested and downloaded part by part and built directly by Mozilla Thunderbird. For this reason it is not possible to write proper information about the infiltrations found into the header and body of the email and thus the functionality is deactivated for this MUA.

To configure ESET Mail Security to scan email messages downloaded from POP3 or IMAP server, run the following script:


Select the POP3 or IMAP install option. This will set the given ESETS module to listen on a predefined port and redirect applicable IP packets. Check the newly added firewall rule to see if any changes are necessary.

Note that the installer backs up all modified configuration files and can display every command that it will execute after your approval. The backup configuration files should be reimplemented after uninstalling. Detailed steps for all possible scenarios are described in ESETS setup and configuration topic of this documentation.
