 Under what types of condition spooling does not take effect?
Article The fail over for any mail systems happens only if your mail server does not respond to ETRN. In some scenarios mail servers or spam filtering gateways respond to ETRN and that is when the fail over mechanism does not happen and the normal email delivery continues. Our general recommendation to avoid such scenarios please make certain that your engineer knows what they are doing and avoid accepting emails or make sure that the appliance would retain accepted emails.
