Sure, but you should be very careful about that or you will block legitimate bounces and probably end up in the rfc-ignorant list. And you should make sure that none of your clients use a MTA (they could send valid bounces) or some redirection/notify/vacation/whatever that uses the empty sender. If you want your "no spams from local users", you could use in your acl_check_rcpt: deny message = no bounces from clients senders = : ! domains = +local_domains Or if your clients do smtp auth: deny senders = : authenticated = * or some other condition to determine people that should never send bounces. But please be careful. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
