Setting up my new email on a Mac?

[Emma H]

I have just been sent details of my new email account for my new job.

The details I have been given are,

Email Account Name (email address)
Password:

Incoming Server (POP3)
Outgoing Server (SMTP)

SMPT address.

Also it says: Outgoing server requires authentication.

I have a Apple G4 Powerbook, Mac OS X 10.3.9.
I tried to open the Mail application, but it 'bounces' in the dock about 3 times, but then stops and doesn't open.

What should I do to set up my email account? Do I need to use the Mail application?
If so, how should I get it to open?

Thanks!!
Yes I updated Safari, which now doesn't work either, so that must be the problem.
Any ideas how to sort it out?
