I have an authoritative domain abc.com, I have an internal relay domain xyz.com.
All users send mail as user@xyz.com, all users primary SMTP address is user@xyz.com
there is no external DNS MX record for abc.com
When users send mail to the internet as xyz.com and cc in other internal users it shows the senders address as @xyz.com but the cc'd in users from the address book as @abc.com.
Why does this happen as all of the primary mail addresses for each user is @xyz.com so that should be sent as that domain internally and externally when picking the user from the gal etc...
