Populate field value to another field in the same table.

[SomyaSwaroC]

I have custom table for storing all the email communication.

1. For inbound emails, sender email address is stored in sender field of the table,
2. For Outbound emails, sender email address is stored in mailbox field.

I want to populate the 'mailbox' field into 'sender' field. So that all are stored in one column. How can i do can someone suggest me the approach?
