New mail never arrives

[chrysalid]

Hello,

I'm trying to help a client, that has an older Mac - running 10.2.8.
Wierdness with her email - She can't check messages - no error, but new messages never show up.
Opening mailbox displays above where messages should be.
I tried logging on to IE webmail using her credentials, and oddly it said the user name/password is incorrect.
I tried on another computer, and it works fine.
I checked that caps lock isn't on, and that I am using the correct credentials.
Any idea what could cause this???

Thanks
Amber

Check the account settings in Mail. Make sure you have the right server info.

New mail never arrives.

Yes - all the account/server information is correct.
I confirmed this before my original post.
What is confusing me is the fact that we can't even log on to webmail from this computer...

There is a message that comes up the first time we try to open the mail -
"Unlock Keychain" - 'Mail wants access to keychain username. Please enter your keychain password or phrase'.

This user has tried the password she uses to boot the computer and the password she uses for mail.
Neither work.

Also - at some point, the test messages we sent of Friday arrived in her mailbox. But no new mail has arrived.

Thanks,
Amber
