Hi Julie

Deleting from the inbox isn’t “standard” practice for email,…so could either be 
something in the account itself or the settings.
How do you have email set up? Is it POP3 or IMAP? (Or Exchange?)
As I have POP3 and IMAP accounts and have never had email deleted from it at 
all.

So might need a bit more info to advise.

As a “short term’” fix, you could create a folder in Apple Mail “On My Mac” and 
put older emails in to folders there,..rather then in the Inbox.
This saves them all on the computer rather then in the Inbox.
(There’s a whole other long post on the benefits of doing this, rather then 
leaving lots and lots of emails in Inbox, Sent etc). Saving them in “On My Mac” 
folders is more beneficial generally).

Is it just an iinet address or another? 
Let us know the above and we can try and help.
Kind regards
Daniel
