Emails to catchall domain (eg. *random*@mydomain.com) are being filtered. Note, the server receives emails to mailboxes normally (eg. [email protected]). mydomain.com is set as a catchall domain sending to [email protected] Adjusting spam filter from "wants all spam" to "uncensored" didn't work. Server sends and receives all other emails normally. I think it has to do with a lmtp setting, but I'm stumped! /var/log/maillog Code: ]# cat /var/log/maillog | grep [email protected] Apr 29 09:53:13 myhost postfix/smtpd[60838]: NOQUEUE: filter: RCPT from mail-yw1-f176.google.com[209.85.128.176]: <[email protected]>: Sender address triggers FILTER lmtp:[127.0.0.1]:10026; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail-yw1-f176.google.com> Apr 29 09:53:13 myhost postfix/smtpd[60838]: NOQUEUE: filter: RCPT from mail-yw1-f176.google.com[209.85.128.176]: <[email protected]>: Sender address triggers FILTER lmtp:[127.0.0.1]:10024; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail-yw1-f176.google.com> Apr 29 09:53:13 myhost postfix/smtp[60841]: D83E11A0FED: to=<admin@mydomain>, orig_to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10025, delay=0.07, delays=0.01/0.02/0.03/0.01, dsn=2.1.5, status=deliverable (250 2.1.5 Ok) Apr 29 09:53:17 myhost postfix/smtpd[60838]: NOQUEUE: reject: RCPT from mail-yw1-f176.google.com[209.85.128.176]: 451 4.3.5 Server configuration problem; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail-yw1-f176.google.com> postconf Code: postconf | grep lmtp lmtp_address_preference = any lmtp_assume_final = no lmtp_bind_address = lmtp_bind_address6 = lmtp_body_checks = lmtp_cname_overrides_servername = no lmtp_connect_timeout = 0s lmtp_connection_cache_destinations = lmtp_connection_cache_on_demand = yes lmtp_connection_cache_time_limit = 2s lmtp_connection_reuse_time_limit = 300s lmtp_data_done_timeout = 600s lmtp_data_init_timeout = 120s lmtp_data_xfer_timeout = 180s lmtp_defer_if_no_mx_address_found = no lmtp_delivery_slot_cost = $default_delivery_slot_cost lmtp_delivery_slot_discount = $default_delivery_slot_discount lmtp_delivery_slot_loan = $default_delivery_slot_loan lmtp_destination_concurrency_failed_cohort_limit = $default_destination_concurrency_failed_cohort_limit lmtp_destination_concurrency_limit = $default_destination_concurrency_limit lmtp_destination_concurrency_negative_feedback = $default_destination_concurrency_negative_feedback lmtp_destination_concurrency_positive_feedback = $default_destination_concurrency_positive_feedback lmtp_destination_rate_delay = $default_destination_rate_delay lmtp_destination_recipient_limit = $default_destination_recipient_limit lmtp_discard_lhlo_keyword_address_maps = lmtp_discard_lhlo_keywords = lmtp_dns_resolver_options = lmtp_enforce_tls = no lmtp_extra_recipient_limit = $default_extra_recipient_limit lmtp_generic_maps = lmtp_header_checks = lmtp_host_lookup = dns lmtp_initial_destination_concurrency = $initial_destination_concurrency lmtp_lhlo_name = $myhostname lmtp_lhlo_timeout = 300s lmtp_line_length_limit = 998 lmtp_mail_timeout = 300s lmtp_mime_header_checks = lmtp_minimum_delivery_slots = $default_minimum_delivery_slots lmtp_mx_address_limit = 5 lmtp_mx_session_limit = 2 lmtp_nested_header_checks = lmtp_per_record_deadline = no lmtp_pix_workaround_delay_time = 10s lmtp_pix_workaround_maps = lmtp_pix_workaround_threshold_time = 500s lmtp_pix_workarounds = disable_esmtp,delay_dotcrlf lmtp_quit_timeout = 300s lmtp_quote_rfc821_envelope = yes lmtp_randomize_addresses = yes lmtp_rcpt_timeout = 300s lmtp_recipient_limit = $default_recipient_limit lmtp_recipient_refill_delay = $default_recipient_refill_delay lmtp_recipient_refill_limit = $default_recipient_refill_limit lmtp_reply_filter = lmtp_rset_timeout = 20s lmtp_sasl_auth_cache_name = lmtp_sasl_auth_cache_time = 90d lmtp_sasl_auth_enable = no lmtp_sasl_auth_soft_bounce = yes lmtp_sasl_mechanism_filter = lmtp_sasl_password_maps = lmtp_sasl_path = lmtp_sasl_security_options = noplaintext, noanonymous lmtp_sasl_tls_security_options = $lmtp_sasl_security_options lmtp_sasl_tls_verified_security_options = $lmtp_sasl_tls_security_options lmtp_sasl_type = cyrus lmtp_send_dummy_mail_auth = no lmtp_send_xforward_command = no lmtp_sender_dependent_authentication = no lmtp_skip_5xx_greeting = yes lmtp_skip_quit_response = no lmtp_starttls_timeout = 300s lmtp_tcp_port = 24 lmtp_tls_CAfile = lmtp_tls_CApath = lmtp_tls_block_early_mail_reply = no lmtp_tls_cert_file = lmtp_tls_ciphers = export lmtp_tls_dcert_file = lmtp_tls_dkey_file = $lmtp_tls_dcert_file lmtp_tls_eccert_file = lmtp_tls_eckey_file = $lmtp_tls_eccert_file lmtp_tls_enforce_peername = yes lmtp_tls_exclude_ciphers = lmtp_tls_fingerprint_cert_match = lmtp_tls_fingerprint_digest = md5 lmtp_tls_key_file = $lmtp_tls_cert_file lmtp_tls_loglevel = 0 lmtp_tls_mandatory_ciphers = medium lmtp_tls_mandatory_exclude_ciphers = lmtp_tls_mandatory_protocols = !SSLv2 lmtp_tls_note_starttls_offer = no lmtp_tls_per_site = lmtp_tls_policy_maps = lmtp_tls_protocols = !SSLv2 lmtp_tls_scert_verifydepth = 9 lmtp_tls_secure_cert_match = nexthop lmtp_tls_security_level = lmtp_tls_session_cache_database = lmtp_tls_session_cache_timeout = 3600s lmtp_tls_verify_cert_match = hostname lmtp_use_tls = no lmtp_xforward_timeout = 300s
Instead of setting it to uncensored, just disable it completely. And are you using amavis or rspamd? If it's rspamd, you might have to tweak the default spamscores.
Hi Th0m, I'm using Amavis. When I turned off "enable greylisting" for each catchall domain, delivery worked! So it appears something is happening with catchall domains and greylisting. Again, emails to a preset address deliver as normal. Note that I'm on CentOS 7.9 and I installed postgrey. Perhaps there's a postgrey misconfiguration?
