中繼到本地 smtp 伺服器時，Postfix 不發送身份驗證

我一直在嘗試讓我的 postfix 伺服器將我的所有消息中繼到本地 SMTP 伺服器。據我所知，我的一切設置都正確，但我得到了一個550 Authentication error. 當我發送帶有發送郵件之類的消息時，我的本地 SMTP 伺服器工作正常，而不是當我使用 postfix 中繼消息時。（我更改了我的憑據/中繼主機名）

這是我的main.cf文件

# See /usr/share/postfix/main.cf.dist for a commented, more complete version
debug_peer_list = 127.0.0.1
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
append_dot_mydomain = no
readme_directory = no
myhostname = evconnect.info
alias_maps = hash:/etc/aliases
virtual_alias_maps = hash:/etc/postfix/virtual
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = localhost
mynetworks = 0.0.0.0/0 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
local_recipient_maps =
relay_domains=*
recipient_delimiter = +
inet_interfaces = all
transport_maps = hash:/etc/postfix/transport

smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/saslpasswd
smtp_always_send_ehlo = yes
relayhost = [localhost]:587

inet_protocols = all

這是我的/etc/postfix/saslpasswd文件預雜湊。

[localhost]:587      user:password
localhost            user:password

在與 Nick 聊天后，問題是 Haraka 只對來自 localhost 的請求宣傳身份驗證。我將 main.cf 中的傳輸文件/relayhost 更改為將我的域引用到 localhost。現在一切正常。
