I got a strange one for you guys: I have 2 websites setup, A.com and B.com I have admin@A.com setup as a catchall I have abc@B.com setup as an email address When I send an email to abc@B.com, it goes to admin@A.com, but when I send to def@B.com (nonexistant account) it bounces. I have tried the FAQ that recommends changing myhostname, it is currently set to example.com, which I don't have any affiliation with, no good. /etc/postfix/main.cf: Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h myhostname = example.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname #mydestination = A.com, localhost.com, , localhost relayhost = mynetworks = 127.0.0.0/8 mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all smtpd_sasl_local_domain = smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom smtpd_tls_auth_only = no smtp_use_tls = yes smtpd_use_tls = yes smtp_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes virtual_maps = hash:/etc/postfix/virtusertable mydestination = /etc/postfix/local-host-names virtualusertable has all the domains set correctly...the catchall is only set for @B.com Ideas? Also: question: does it matter what the setting under Management -> Server -> Settings -> Domain is?
