Q:

How can i find hardcoded(?!) Store Mail

The Store is defined under magentoA.com but the Store Mails (Newsletter, orders, etc) is on shop@developer.com - i think i don't have to say that this is a pity.
So even if i change the store mails it doesn't change - i think these mails are hardcoded?
May someone can give me a hint -
mailq (@debian sys) is showing me that something is sent by this shop@developer.com (www-data) may this gives someone an idea?

A:

Admin > System > Configuration > Store Email Addresses look here, check all store scopes, set them to desired email.
You may also want to double check Admin > System > Configuration > Advanced > Mail Sending Settings and/or attempt to determine wether or not you're using an extension that offloads mail sending to something other than your localhost.
