Cache Settings

The 'Cache' settings tab allow administrators to set the cache expire time for Greylist IP addresses, SMTP Auth logs and LDAP.

• To open the 'Cache' settings interface, click the 'System' tab on the left menu then 'Settings' and 'Cache' tab.

• Greylist IP Cache expire time: Secure Email Gateway greylists IP addresses from which emails are received for the first time and rejects it. If the sender is using a proper mail server, it automatically resends the email. The greylisted IP becomes whitelisted and email is not rejected. If the mail is from a spam source, then normally it will not resend mails. Enter the time for which the greylisted IPs should be cached. If within this time emails are resent from greylisted IPs, they are whitelisted. After the entered time, the greylisted IPs are deleted from the greylist. 

• SMTP AUTH logs expire time: The end user authentication log details of SMTP clients are cached for the entered days and after that they are deleted.

• LDAP Cache: LDAP authentication details are cached and Secure Email Gateway does not query the LDAP server. 

• Click the 'Clear Now' beside an item to clear the cache immediately.

• Click 'Save' to apply your changes.
