postfix error Relay access denied. trying to setup virtual domains
periferral
I am trying to get postfix working as a part of my email server. I am
running this on debian and using LDAP. Here is the output of my
configuration
dns:/etc/postfix# postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
content_filter = smtp-amavis:[127.0.0.1]:10024
inet_interfaces = all
mailbox_size_limit = 0
mydestination = dns.example.com, localhost.example.com, , localhost
myhostname = dns.example.com
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost =
smtp_sasl_auth_enable = no
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
smtpd_sasl_auth_enable = yes
smtpd_tls_auth_only = yes
smtpd_tls_cert_file = /etc/ssl/CA/keys/example.crt
smtpd_tls_key_file = /etc/ssl/CA/keys/example.key
smtpd_tls_session_cache_database = btree:${data_directory}/
smtpd_scache
smtpd_use_tls = yes
virtual_alias_maps = ldap:ldapalias
virtual_gid_maps = static:999
virtual_mailbox_base = /home/vmail
virtual_mailbox_domains = ldap:domains
virtual_mailbox_maps = ldap:accounts
virtual_minimum_uid = 999
virtual_transport = dovecot
virtual_uid_maps = static:999
The LDAP stuff seems to be working fine.
dns:/etc/postfix# postmap -q exa...@example.com ldap:accounts
example/,postmaster/
dns:/etc/postfix# postmap -q exa...@example.com ldap:ldapalias
exa...@example.com,postm...@example.com
dns:/etc/postfix# postmap -q exa...@example.com ldap:domains
example.com,example.com
dns:/etc/postfix#
However, when I send an email from an external address to postfix, I
see this in my error logs
Oct 15 15:34:38 dns postfix/smtpd[8639]: connect from smtp1.company.com
[208.70.196.45]
Oct 15 15:34:38 dns postfix/smtpd[8639]: NOQUEUE: reject: RCPT from
smtp1.company.com[208.70.196.45]: 554 5.7.1 <exa...@example.com>:
Relay access denied; from=<us...@company.com> to=<exa...@example.com>
proto=ESMTP helo=<smtp1.company.com>
Oct 15 15:34:43 dns postfix/smtpd[8639]: disconnect from
smtp1.company.com[208.70.196.45]
If I add mydomain to mydestination, the local transport takes over and
it seems to work. However I want to user virtual transport and I'm
having no luck with it.
Any help is appreciated.
thanks
Dan

I do the following
relay_domains = $config_directory/relay_domains
then in the file "relay_domains", just list the domains that you want
to relay, one per line.
I haven't setup postfix with ldap yet, but I'm sure there is an entry
for relay domains if you don't want to put it in a text file. Then
again if its just one domain, you can save an ldap lookup by putting
it in a flat file.
