## ======================================================================================
##      !!!          please define or confirm the following three vars           !!!
##      !!!           before using the msmtpq or msmtp-queue scripts             !!!
## ======================================================================================
##
## only if necessary (in unusual circumstances - e.g. embedded systems),
##   enter the location of the msmtp executable  (no quotes !!)
##   e.g. ( MSMTP=/path/to/msmtp )
MSMTP=msmtp
#[ -x "$MSMTP" ] || \
#  log -e 1 "msmtpq : can't find the msmtp executable [ $MSMTP ]"   # if not found - complain ; quit
##
## set the queue var to the location of the msmtp queue directory
##   if the queue dir doesn't yet exist, better to create it (0700)
##     before using this routine
##       e.g. ( mkdir msmtp.queue      )
##            ( chmod 0700 msmtp.queue )
##
## the queue dir - modify this to reflect where you'd like it to be  (no quotes !!)
