How to get correct "From address" of incoming messages

In PMG, I create an action "disclaimer" to insert the sender's address into the message body for inbound messages:
Code:
[----- This email send from external address: __SENDER__ -- please review before any action, clicking on links, or opening attachments -----]

However, in some cases, these addresses don't match what I see in the Zimbra web interface. For example:

  • The message in PMG shows a 'From' address of infoiratc@gmail.com,
  • but in Zimbra, it shows a 'From' address of mdalikoc4@gmail.com

Mesage header in ZImbra:

Code:

My question is: Which address is the real sender address, and how can I view both addresses in PMG?

Thanks.
 
Hello @Squiggle,

Real sender is infoiratc@gmail.com. You can find it in header:
Code:
Received-SPF: pass (gmail.com ... _spf.google.com: Sender is authorized to use 'infoiratc@gmail.com' in 'mfrom' identity (mechanism 'include:_netblocks.google.com' matched)) receiver=mail.server.name; identity=mailfrom; envelope-from="infoiratc@gmail.com"; helo=mail-ej1-f41.google.com; client-ip=209.85.218.41

Zimbra shows sender in 'From' header, it may not be the real sender.
PMG shows sender in 'Return-path', that's the real sender.
