I am attempting to edit the SOGo configuration file located at
data/conf/sogo/sogo.conf to include the parameter
SOGoMailSignaturePlacement = above; as specified on page 58 (PDF page 61) of the SOGo Installation Guide [https://www.sogo.nu/files/docs/SOGoInstallationGuide.pdf]. However, despite adding this line and restarting the SOGo container with the memcached, the signatures are still appearing below when I try to reply to an email.
I would greatly appreciate it if someone could provide me with a solution or insight into what I might be doing wrong.
