By this I mean:
I see in /var/log/maillog that Mary is sending and receiving mail
but /var/spool/mail/mary has not grown since Nov 1 1813 hr
We don't have mail quotas and her inbox is not full <snip>
Firstly, has Mary recently got married/divorced and changed her surname? That's always a 'gotcha' for admins resulting in hours of futile error-hunting the first time!
You might want to check if a message sent to Mary generates a bounce back to the originator; if so it should give you a clue.
The next thing to check is that Mary's email client is correctly configured to receive. Check that the servername is correct and that any username/password is correct too if it's been saved by the client.
