Sending mail as a particular user

["McRae, Darren A" <darren.mcrae@cgey.com>]

Hello,

Is the a way of mail being sent as a particular user no matter what the
linux username is? So if I log in as root or daz or pete it sends mail
signed as sales@mydomain.com.

This needs to be done via sendmail, as that is what I'm using.

regards

Darren
