hello,

I have configured a mail server with Sendmail.

When I am sending/receiving mails from the same IP block the server is located in, its working quite fine.

But when I am sending/receiving mail from a different IP block its taking a some time to get connected to the server and also authorizing the user.

I do have a Router in the network.

When I was using WIN NT as Mail Server, it wasnt like this. It has started after using linux.

Why this is happening and what are the possible solutions?

Can any one PLS help me.

Thanks.

Tahmeed
