Sorry - been fighting heat and hardware problems on this server ... Point w/r MeTA1 - there you go. TWO implementations each of which work only to themselves. Perhaps MeTAl has a more elegant approach. Or not. But does it stay within the allowance for experimental extensions as well as Courier? Plus - it is still early days for the MeTAl project, whereas courier-mta has been around for donkey's years. -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
