If you have also enabled Recipient Address Verification (see “Configuring recipient address verification”), the FortiMail unit does not form quarantine accounts for email user accounts that do not exist on the protected email server. In that case, invalid quarantine accounts are never formed, and this option may not be necessary, except when you delete email user accounts on the protected email server. If this is the case, you can improve the performance of the FortiMail unit by disabling this option. |
