I'm hoping someone can help me with Postfix/Dovecot SMTP authentication.
When trying to send a test message with a mail client over the internet I get the following error:
Code:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was username@gmail.com'. Subject 'test', Account: 'mailgw.mydomain.com', Server: 'mailgw.mydomain.com', Protocol: SMTP, Server Response: '554 5.7.1 <username@gmail.com>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79
The g-mail account is the address I'm sending to. The account i'm sending from has an account on the server and I can successfully download messages using this client. I can also log in to squirrelmail using this account. So I know that dovecot is authenticating it.
Ideally I would like anyone that can authenticate from domain example.com to be able to send mail through my server.
Below are what I think are the relevant portions of my main.cf and dovecot.conf file.
Main.cf
----------
Code:
virtual_mailbox_domains = /etc/postfix/virtual_config/virtual_domains
virtual_mailbox_maps = hash:/etc/postfix/virtual_config/virtual_mailboxes
virtual_mailbox_base = /var/spool/virtual_mail
virtual_minimum_uid = 100
virtual_uid_maps = static:501
virtual_gid_maps = static:501
virtual_alias_maps = hash:/etc/postfix/virtual_config/virtual_aliases
smtpd_sasl_auth_enable = yes
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
broken_sasl_auth_clients = yes
#smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination
smtpd_sender_restrictions = permit_sasl_authenticated, permit_mynetworks
Dovecot.conf
----------------
Code:
auth default {
# Space separated list of wanted authentication mechanisms:
# plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi otp skey
# gss-spnego
# NOTE: See also disable_plaintext_auth setting.
mechanisms = plain login cram-md5
passdb passwd-file {
# File contains a list of usernames, one per line
args = /etc/postfix/virtual_config/virtual_passwords
#args = /etc/dovecot.deny
#deny = yes
}
userdb passwd {
}
userdb static {
args = uid=501 gid=501 home=/var/spool/virtual_mail/%d/%n
}
socket listen {
#master {
# Master socket provides access to userdb information. It's typically
# used to give Dovecot's local delivery agent access to userdb so it
# can find mailbox locations.
#path = /var/run/dovecot/auth-master
#mode = 0600
# Default user/group is the one who started dovecot-auth (root)
#user =
#group =
#}
client {
# The client socket is generally safe to export to everyone. Typical use
# is to export it to your SMTP server so it can do SMTP AUTH lookups
# using it.
#path = /var/run/dovecot/auth-client
path = /var/spool/postfix/private/auth
mode = 0660
user = postfix
group = postfix
}
}
}
Any help is much appreciated. This server hosts e-mail for multiple domains and it's done with virtual users.
