I have also had a run in with the ATO recently.
It appears that the ATO cannot send emails to people where their email address is in lower case.
When staff enter email addresses of tax payers into their systems they are automatically converted to upper case.
Really strange things is that they ATO requests that emails sent to them are in LOWER CASE.
