Funny, I have tried your suggestion.. but the same problem still occurs.. when I try to send mail to local network, the error message is as follows:

The connection to the server failler, Account 'Winan' server:192.11.21.1,, protocol SMTP, port 25, secure (SSL): No. socker error 10061, error number: 0X800CCC0E

once again to inform you, that I use RedHat 7.2 and Outlook express to retrieve and send email..

any other solutions?

Regards
Winan
