Give me once more help, please!

Hello,
www4mail@wm.ictp.trieste.it  more than 3 days does not answer
on my inquiry, for example

GET http:/www.lebed.com/lebed.htm

Also does not inform about errors :-(

And today my mail server answered:

>   ----- The following addresses had permanent fatal errors -----
>   www4mail@wm.ictp.trieste.it
>   ----- Transcript of session follows -----
>   550 www4mail@wm.ictp.trieste.it... Host unknown (Name server:
    wm.ictp.trieste.it: host not found)

What me to do, advise!

Thanks,
---
