Hi, I have written a system which sends out email to a database.
Recently I have been experiencing major performance problems. The software I have written and use has remained unchanged so I suspect I have a problem with DNS resolutions on my Linux box. The emails themselves do get delivered correctly but the process takes hours rather than minutes. I have contacted my hosting provider and they have said that there is a reverse lookup address in their DNS. Can anyone help me find out and test if the DNS the system is using is configured correctly? Does anyone know how I can track down the reason for the performance bottleneck? I have also check my resolv.conf file and both the primary and secondary DNS are specified there. Can anyone help?
