When scanning or relaying the email fails (e.g. the internal processing component or the relay SMTP server is not available), Email Gateway Security will retry.
Under Settings > General / Retry the retry count and the interval between each attempt can be configured.
SMTP servers
Email Gateway Security’s inbount SMTP server port and the SMTP server’s encryption configuration has been moved to under Settings > Security General / SMTP Server Connection Settings.
Email Gateway Security can listen on multiple SMTP ports providing the option to apply different settings for each SMTP port.
Anti-spam
With the Agressiveness level Email Gateway Security’s anti-spam component can be configured how eager it should be when looking for (potential) spam.
Enabling the Add analytical email headers Email Gateway Security will add special headers to emails so that later it can track false positive or negative spam.
In the IP whitelist a list of IPv4 addressess can be specified for which anti-spam checks will be bypassed.
License
Automatically assign license to users
Email Gateway Security is capable to automatically discover users and count them for licensing using machine learning techniques. To enable automatic user discovery turn Settings > General / Licensing / Automatically assign license to users on.
Only license users from Active Directory
Email Gateway Security can have a tight integration with Active Directory (or other LDAP based directory services). Enabling Settings > General / Licensing / Only license users from Active Directory will make the product to refuse all recipients (for inbound rules) and senders (for outbound rules) that do not exist in the Active Directory.
Licensing non-existing users
Licensing users from Active Directory only can eliminate the risk that non-existing users will be counted for license.
For further details see 1. Licensing and 4.6. Server profiles.
Syncronize licensed users with Active Directory
Enabling this setting will sync licensed users with users in Active Directory. If certain users have been removed from the Active Directory then those users get unlicensed in Email Gateway Security, too.
Sync time
Synchronization runs once every day at midday according to the server time.
On-demand synchronization to Active Directory is also available. For details see 5.9. User based licensing.
