You can only send data as fast as the system on the other end can accept it, and the network link can support. If that's slow, nothing you can do about it. Some large isp's systems are very slow. Hotmail, Yahoo, and others come to mind.

Hi,

If the initial banner line (the first response you get from an email-server after running telnet 0 25) takes a long time to return, then chances are you have a problem with something DNS related. This could be either your DNS server looking up your systems hostname, or a mapping table lookup of an external DNS blacklist of some kind.

We have seen this problem a number of times.

What do you have in your PORT_ACCESS mapping table and when the system is 'hanging', what do you get for output of the command "./imsimta dispatcher_stats_tty"

Regards,

Shane.
