This is a basic security check that some systems do - e.g. if I claim to be from 192.168.100.23, and 192.168.100.23 resolves to 'happyhost@hunter.com', but 'happyhost@hunter.com' when nslook'd up turns out to be '120.39.29.1' - then I'm probably not who I claim to be... The pause is while all the DNS activity is going on... Some systems will kick you out if you fail this check, others will just log it as a 'warning'. Check your IP address is reverse-resolvable, and that your hostname can be put through a DNS lookup on both systems...
