argh .. hatte ich übersehen, sorry ...
Das sieht also jetzt so aus:
smtpd_delay_reject = no
smtpd_recipient_restrictions = 
		permit_sasl_authenticated
		permit_mynetworks
		permit_tls_clientcerts
		check_sender_access hash:/etc/postfix/whitelist
		check_sender_access regexp:/etc/postfix/tag_as_originating.re
		check_sender_access regexp:/etc/postfix/tag_as_foreign.re
		reject_non_fqdn_hostname
		reject_unknown_reverse_client_hostname 
		reject_unauth_destination
		reject_rbl_client cbl.abuseat.org 
		reject_rbl_client zen.spamhaus.org
smtpd_sender_restrictions =

da find ich eben nix .... und ich versteh es nicht, wie der Spammer das macht.

allerdings hab ich das hier drin:
virtual_mailbox_domains = hash:/etc/postfix/virtual_domains_dummy
und da steht:
dummy.local allow
drin
das war wegen einem bug in der MacOS implementierng, kann mich aber nicht mehr erinnern, was das genau war.

ich kann mich nur an das hier erinnern:
smtpd_delay_reject = no
das hab ich eingefügt.

wie kann ich das mit der Mailadresse verhindern?
