Email Address - Need to Modify

[erconway1943]

Hi all. My original email account was with SWBell when I purchased my iMac. I have since changed to Yahoo. Everytime I have to respond, the autofill features 'sees' my previous account. Where do I go to change this? Your wisdom will be appreciated. Thank you.

I'll save the sarcastic comment and just ask, What email program? Assuming you're using Mail.app then go to preferences>composing and find the drop down for new messages from <new email address>.

Boom.
