Fileshare FROM email address not SMTP configured one

Hello all,

we are facing following issue with our Serv-U installation.

When Sending or Requesting files via File Share, the sender email address (FROM) is set to the user sending the request and not to the SMTP FROM address configured in the system.

We are using LDAP, so the contact details are populated from the AD.

Our SMTP server needs its FROM email address in certain format, which is different than the email address pulled from AD.

Any advice how to override this?

Thank you
