I'm thinking about how it works... I use the email [email protected] and put in some aliases, lets say fritz/heinz/karl. First, for ISPConfig, is it correct then, that [email protected] will collect [email protected] ...too? Second, if I don't use catch all for this account but this is my only mailadress for the domain firma.de...would other mails like [email protected] automatically get bounced or would they stay somewhere until there is an catch all account that collects them? Third, would it then be enough to put an anti-spam config like the following into main.cf to get rid of unused mails? Code: bounce_template_file = /etc/postfix/bounce.cf delay_warning_time = 30m bounce_queue_lifetime = 3d maximal_queue_lifetime = 3d smtpd_sasl_local_domain = smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_helo_required = yes disable_vrfy_command = yes strict_rfc821_envelopes = yes invalid_hostname_reject_code = 554 multi_recipient_bounce_reject_code = 554 non_fqdn_reject_code = 554 relay_domains_reject_code = 554 unknown_address_reject_code = 554 unknown_client_reject_code = 554 unknown_hostname_reject_code = 554 unknown_local_recipient_reject_code = 554 unknown_relay_recipient_reject_code = 554 unknown_sender_reject_code = 554 unknown_virtual_alias_reject_code = 554 unknown_virtual_mailbox_reject_code = 554 unverified_recipient_reject_code = 554 unverified_sender_reject_code = 554 smtpd_client_restrictions = smtpd_helo_restrictions = smtpd_sender_restrictions = smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination, check_policy_service inet:127.0.0.1:60000, reject_unauth_pipelining, reject_invalid_hostname, reject_non_fqdn_sender, reject_unknown_sender_domain, reject_non_fqdn_recipient, reject_unknown_recipient_domain, permit
