It seems that the parser is too old (20 years?) in procmail. The solution is to put a "; :" at the end of the command so we need to change from
LENGTH=`echo ${#VAR}`
to
LENGTH=`echo ${#VAR} ; :`
which execute directly
bash -c "echo ${#VAR}"
and then it works. Since AFAIK ${#VAR} is POSIX, I think,
this should be noted in the "procmailrc" or "procmailex" manpage.
Thanks, Greetings and nice Day
