Ok and how is your SMTP configured on the client that faults?

It is using mdaemon as SMTP or an outside SMTP server? (probably your ISP's)

Ah it is not configured to ping....

What if you put the ip address and name in the hosts file on that machine like. (guessing here the ip adress is 1.1.1.1)

1.1.1.1       mail.iradio.ie

Save and try to mail again.

(hosts file is located in windows\system32\drivers\etc)

Ok, what if you compare SMTP settings on a not working machine with a right working machine?

Or what if you temporarily disable the firewall to test?

Then there are two more options, the connections is blocked by a firewall OR by a antivirus(or antispam) solution.
