I am having a challenge setting a working mail solution for my site.  My mail provider is part of my corporation and they will not allow me to relay from their SMTP servers.  My corporation controls the DNS configurations and have strict policies regarding what is allowed.  I have setup an account with authSMTP and my DNN Administrator user is authorized to send messages via authSMTP.  Under Host, SMTP, I set the host settings to the authSMTP servers and perform test, and the email works as my Host Email account is set to the authozed sender.

When I go to Log in, and forget password and have a password emailed to a user, the systems "envelope from" settings is using the Users email address, not the administrators address.  Therefore authSMTP is not allowing this email to be transferred.  There tech support sent me this message:

"You can either change the email settings so that the 'envelope from'  address matches the 'from' address or you can register  users email as an authorised sender for your AuthSMTP Account."

When I setup a localhost SMTP and send an email out to my account it generally works, but due to the MX records configurations I cannot rely on this setting as mail will become taged as spam, or registered under the Mail-Abuse.  Here is my localhost headers when a successful email is sent:

When I create a new user and use my authorized email account, which is the same as the admin's account, I can get my password emailed to me.  I have my system configured to allow nonunique emails.

Do I need to update the Mail Services code to resolve this issue ?

The release of the community editin 5.4.1 seems to fix the Mail From to be the System Administrator.  The release 5.4.0 seems to have an issue with Mail From as the users email account.
