Your college email gives you the ability to manage lists of email addresses and domains that you want to block or allow emails from.
To get to the Junk email settings from your inbox: Click on Options, then Select Block or Allow.
Messages that are received from any email address or domain on your Blocked Senders List are sent directly to your Junk Email folder.
To add a sender to the Blocked Senders list
In the Blocked Senders list, type an email address or domain in the text box, and then press Enter.
To add a sender to the blocked senders list, in an email message you've received from that sender, right click on the sender's name, select Junk Mail, then choose Add sender to blocked senders list. This will automatically send all incoming emails from this sender to your Junk email folder.
This list will contain domains and email addresses that you choose are safe for you. Any email coming from the domain or email in this list will be directly delivered to your Inbox.
There will be an automatic delete from the deleted items and junk email folders after about 14 days.
