add variables into body inline message (-M)

[mfran2002]

Hi all,
if I try this:

set mytime="TIME/T"
set message="mail sent at %mytime%"

mailsend1.19.exe -starttls -smtp mysmtp -port 25 -auth -user mymail -password mypwd -t myreceipt +cc +bc -f myfrom -sub "%message%" -M "%message%"

it gets me error

is it possible to put some variables into inline subject (-sub) and body (-M)?

thanks
