[X-Newbies] Receiving email

[Tom Garrou]

I have a friend with an early version of iMac, running the current  
version of OS X and using Mail as her email application.  She is able  
to send email but not receive it.  As far as I can determine her  
entries in her email account are accurate.  Her internet provider  
says it is a Mac problem and have not been able to help her solve her  
problem.
I am at a loss on how to go about solving this problem and would  
appreciate any suggestions anyone on this list could provide.

Thanks in advance.
