Actual behavior

exemple
in this screenshot, the customer answer Carole agent email, but we can see in its email content that the From field was set to Céline agent
The communication log for article 96 is clean

This behavior was first seen in 6.0.29 version (https://community.znuny.org/viewtopic.php?f=62&t=42026&p=178375)
