# Overriding the "From" field

To set a custom email address and sender name on a message you intend to send, enable View From Override Field and change the default sender name and email address in the corresponding fields.

This functionality can be useful for wildcard mailboxes when using qmail and sub-addressing.

Setting an arbitrary address might collide with your email provider's Sender Policy Framework and/or DomainKeys Identified Mail restrictions.
