Issue
Solution
Many email clients are compatible with various ESET products for Windows. If an email client is compatible with ESET products, regardless of the protocol used, all email received is scanned for threats and spam (in programs with the antispam feature). Additionally, the ESET Endpoint Security toolbar and ESET Antispam toolbar will display in the email client.
List of compatible email clients
To determine which ESET product is best suited to your needs, locate your current email client in the Email Client column and view the compatible ESET software in the adjacent rows (indicated by the green check marks 
).

[1] Scan for sending is not supported for ESET Endpoint Security / Antivirus 9.1 and later and ESET Windows home products 15.2 and later
[2] While using Windows 10 Mail app, emails may not be scanned for spam. ESET products will scan POP3 and IMAP emails for the presence of malicious code.
[3] With Windows Live Mail 2011/2012, although no ESET icon appears in the taskbar, the plugin is otherwise fully functional.
[4] ESET products will scan POP3/POP3S and IMAP/IMAPS email for the presence of malicious code while using Mozilla Thunderbird 6+ or other email clients not listed above. Email may not be scanned for spam, however.
Troubleshooting
If you are using an email client that is supported by ESET Smart Security Premium, ESET Smart Security or ESET Internet Security but you cannot see the Antispam toolbar in your email client, reintegrate the toolbar.
