That is not the question you've asked before (see quota above).

The manual page mentions a ~/.claws-mail/customheaderrc file, and in the
source code you could learn how that file is used. Quickstart:

$ grep customheaderrc * -R
doc/man/claws-mail.1:$HOME/.claws\-mail/customheaderrc
src/common/defs.h:#define CUSTOM_HEADER_RC	"customheaderrc"
tools/README:      		echo "0:" `cat filename.xface` > ~/.claws-mail/customheaderrc
$ grep CUSTOM_HEADER_RC * -R
src/prefs_customheader.c:			     CUSTOM_HEADER_RC, NULL);
src/prefs_customheader.c:			     CUSTOM_HEADER_RC, NULL);
src/common/defs.h:#define CUSTOM_HEADER_RC	"customheaderrc"

I haven't used that file before, so perhaps the theory is far off reality.

The versions don't seem to be hardcoded, though, so as a brute-force hack,
it would even be possible to "sed -i" the executable and replace the build
target string (provided that you don't mess up its length):

$ strings /usr/bin/claws-mail |grep GTK\+
X-Mailer: %s (GTK+ %d.%d.%d; %s)
X-Newsreader: %s (GTK+ %d.%d.%d; %s)
runtime GTK+ %d.%d.%d / GLib %d.%d.%d
buildtime GTK+ %d.%d.%d / GLib %d.%d.%d
GTK+ %d.%d.%d / GLib %d.%d.%d
$ strings /usr/bin/claws-mail |grep redhat
x86_64-redhat-linux-gnu
