this makes no sense the reason for the lifetime is simple and if 5 days is to long for you set the global value lower - wie did for 3 days * connection refused have you ever migrated big servers, dns and so on? 6 hours are are too less for kill all mails if a nameserver lives on the mailhost and is the main server for the domain-record of the machine the old answers have a TTL of two days and you have no option do do anything to make this faster (google for glue-record) * connection timeout sometimes there are troubles the only one where it makes sense to reduce is for dns-errors because there are always two nameservers or more and if the gone away longer than a day the domain is dead or the reason happens not often if the domain is still alive and has troubles
