If you chose to leave your email on the server (or maybe your email client did this without your knowing! ) then eventually your account will fill up and use all the allocated disk space.
This means that any new email to you could bounce back to the sender telling them that your mailbox is full.
To adjust your settings so that this does not happen follow these simple steps:
OS X Mail:
- In the Mail App, go to the Mail Menu in the top bar and pick 'Preferences'
- In the Preferences Pane, Pick the 'Accounts' Tab
- Select your account on the left and then the Advanced Tab on the right
- Tick the box 'Remove copy from server after retreiving a message:'
- Under this Select the time-frame you want to leave them on the server for.
- Close the Prefences Pane and Save
- Go to Tools Menu and select 'Account Settings'
- Select your Account and click 'Change'
- In the settings screen. select 'More settings'
- In the More settings Pane, select the 'Advanced' Tab
- Either remove the tick in the box 'Leave a copy of messages on server' or
- Tick the box 'Remove from server after X days' and set the number of days you want to leave messages on server
- Click OK and then Finish to save.
- Go to File Menu, select Info on the left and select 'Account Settings'
- Select your Account and click 'Change'
- In the settings screen. select 'More settings'
- In the More settings Pane, select the 'Advanced' Tab
