You can select one or several scan engines:
- Anti-Virus.
- Anti-Spam.
- Anti-Phishing.
- Content Filtering.
- Personal denylist of addresses.
- Link scanning.
- Mail Sender Authentication.
- KATA (displayed only when KATA integration is configured).
Scan engines can be combined with the logical "AND" operator.
Sender email
contains
Text for searching sender email addresses. The addresses to be searched are taken from the SMTP session.
You can enter an email address (for example: example-email@example.com), domain name (for example: example.com) or several symbols from the email address (for example: exa).
If you have configured LDAP server integration, the application searches for LDAP cache records matching the entered search string and displays a tooltip with account names.
Sender IP
