My reply template results in quoted headers that show the current date and time, not the date and time the message I'm replying to was received. It doesn't matter what reserved words I use. Despite what Marky Mark DE says in his review, even %datelocal% gives the wrong result.
This is my reply header:
Subject: %subject%
Date: %datelocal%
To: %to%
From: %from%

I must be doing something wrong. Anybody any idea?
