Outlook express POP3 client setting and Lotus Notes Domino server

Dear all,

I would like to connect Lotus Notes Dominio Server to my Outlook
Express POP3 or IMAP

client.

A have the full access to the Lotus Notes V5.09A client, and I know
that Domino server has

been enabled to provide a SMTP & POP3 server services.

The problem is that I know that the Domino server address in in the
form:

server123/M/SERVER/COMPANYNAME

and I don't know how translate the full addresss the a right Outlook
espress server name

I can ping the server123 and it return a specific IP address, but if I
put this number in the

Outlook express account setting it doesn't work

Best Regards,
Paolo
