我有一个安装了 Directadmin 的 VPS，它还安装了 Exim。我尝试对其进行配置，以便允许机器上托管的网站通过 Exim 进行中继。我已为 Exim 配置了智能主机。
但是，当我尝试让网站通过本地主机发送邮件时，它会要求进行身份验证。我已将以下内容添加到主机列表中
hostlist relay_from_hosts = ::1
并将以下内容添加到 ACL
accept hosts = +relay_from_hosts
endpass
这是完整的 ACL：
######################################################################
# ACLs #

begin acl
# ACL that is used after the RCPT command
check_recipient:
## My own Edit.
accept hosts = +relay_from_hosts
endpass

# local parts begin with a dot or contain @ % ! / |
deny domains = +local_domains
local_parts = ^[.] : ^.*[@%!/|]
# to restrict port 587 to authenticated users only
# see also daemon_smtp_ports above
accept hosts = +auth_relay_hosts
condition = ${if eq {$interface_port}{587} {yes}{no}}
endpass
message = relay not permitted, authentication required
authenticated = *
# allow local users to send outgoing messages using slashes
# and vertical bars in their local parts.
# Block outgoing local parts that begin with a dot, slash, or vertical
# bar but allows them within the local part.
# The sequence \..\ is barred. The usage of @ % and ! is barred as

# commented out. However, if you'll be telling your senders of blocked
# email to send an email to [email protected], then you should
# replace "errors" with the left side of the email address you'll be
# using, and "example.com" with the right side of the email address and
# then uncomment the second two lines, leaving the first one commented.
# Doing this will mean anyone can send email to this specific address,
# even if they're at a blocked domain, and even if your domain is using
# blocklists.
