Qmail smtp slow

Hi,

Apologies if this has been covered before, but my qmail smtp server is acting very slow. If I telnet to port 25 on localhost it's quick, but if I do the same from a remote machine It takes ages to respond. I'm guessing it's a DNS problem, but the server's name resolves OK, as does the machine I'm coming in from. Does anybody have any ideas? Your help would be very much appreciated.

Thanks
Jez
