Takes a long time to connect to mail server?
I have a problem with our mail server where it sometimes take some of our users 30 seconds to connect to send/recieve mail and also somethimes connecting in FTP.
I understand this is due to our server is having a problem doing a
reverse lookup on the users IP address (usally people using ADSL have this problem). It seems a stange thing as if the reverse lookup fails it just times out after 30 seconds and let them connect.
Does anyone know how to stop this?

Server is a Linux Redhat 7.2 / send mail etc......
