Forwarding Emails with Full Headers

Fowarding emails with full headers allows the CUIT Service Desk or Security team to troubleshoot an issue more clearly. Your email password and other personal information is not included in the full headers.

There are a variety of situations when you may need to redirect an email message you've received from someone else, at the same time preserving the header information of the original message. The message header includes information about:

  • Who sent the message
  • From where it was sent
  • Postmaster information
  • Subject
  • Date
  • Reply-to address

By preserving the original headers, the person to whom you pass the message can reply directly to the original sender. Or, a technical person can investigate where the original email came from, helpful for when the message is suspected to be spam or to include a computer virus.

Different mail programs use different commands to perform the function of passing on a message with the original headers: it could be redirect or resend or bounce. Below is a list of mail programs and the specific instructions for performing this function. If your email program is not below, we suggest checking's comprehensive list.
