Getting alert Emails from root and not from name i configured.

Further to an upgrade from 10.2.3 to 11.6.0, I am seeing the same change in behavior. In 10.2.3, the configured "fromaddress" in /config/user_alert.conf was used for the sender's name and email address: From: [email protected] [mailto:[email protected]] However, in 11.6.0, it is only used for the sender's email address - the sender's name is now "root". From: root [mailto:[email protected]] I'm happy everything is configured okay but am keen to retain the original behaviour. Any ideas? Paul
