Postfix configuration issue with Debian Etch

[higene]

I thought I'd be clever and rebuild my mail server(formerly Debian Sarge) and install Debian Etch(using the Perfect guide). The server is chugging along happily, but postfix is not allowing email in to my users. I set up Maildirs and can receive local email, but outside emails to my users@mydomain.com are blocked. The message is relay access denied. I should know how to fix this, but several hours of lurking through the forum archive later, I must admit that I could use some expert advice. Sending email from my pop3 client is working properly.

Here is my postconf -n output:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
broken_sasl_auth_clients = yes
config_directory = /etc/postfix
home_mailbox = Maildir/
inet_interfaces = all
inet_protocols = all
mailbox_command =
mailbox_size_limit = 0
mydestination = brat01.brat.com, localhost.brat.com, localhost.localdomain, localhost
myhostname = brat01.brat.com
mynetworks = 127.0.0.0/8
myorigin = /etc/mailname
recipient_delimiter = +
relayhost =
smtp_tls_note_starttls_offer = yes
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
smtp_use_tls = yes
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject _unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain =
smtpd_sasl_security_options = noanonymous
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtpd_tls_auth_only = no
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtpd_tls_session_cache_timeout = 3600s
smtpd_use_tls = yes
tls_random_source = dev:/dev/urandom


Thank you in advance. Your forum is invaluable to the community.

I don't see any virtual_maps directive in your Postfix configuration...

Do you use ISPConfig?

[higene]

I am not using ISPconfig. I had set it up under Sarge, but with a single domain to administer, I thought it was more than I needed.

I find that if I add mydomain.com to my mydestination directive, then everything works. Is setting a virtual_maps directive a better technique?

Thanks for the feedback.
