我想使用主机后缀安装从Alpine PHP Fpm容器发送邮件。
重述
PHP Fpm容器->发送邮件->主机上的PostFix->通过SMTP 发送
但我有
sendmail:无法连接到远程主机(127.0.0.1)：连接被拒绝
这是Postfix配置：
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
append_dot_mydomain = no
readme_directory = no
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = MYDOMAIN.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = localhost.com, localhost
# SMTP authentication settings
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = static:no-reply@MYDOMAIN.com:SECRETPSW
smtp_sasl_security_options = noanonymous
smtp_tls_security_level = may
#header_size_limit = 4096000
relay_destination_concurrency_limit = 20
# Limit DOS Attacks
default_process_limit = 100
smtpd_client_connection_count_limit = 10
smtpd_client_connection_rate_limit = 30
queue_minfree = 20971520
header_size_limit = 51200
message_size_limit = 10485760
smtpd_recipient_limit = 100
# Default relayhost setting
relayhost = smtp.MYDOMAIN.com
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 172.18.0.3 # Fpm container IP
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = 172.18.0.1 # Docker0 bridge IP
inet_protocols = all
这是php.ini邮件部分：
[mail function]
SMTP = localhost
smtp_port = 25
sendmail_path = "/usr/sbin/sendmail -t -i"
mail.add_x_header = On
我需要在docker compose文件或主机防火墙设置中打开任何端口吗？
我不确定是否使用主机的config/postfix，但我可以建议一个同样有效的替代解决方案。添加一个postfix容器并将配置从主机复制到容器：
services:
application:
image: some-company/some-application
environment:
- APPLICATION_ENV
ports:
- 80:80
smtp:
image: namshi/smtp
environment:
- MAILNAME
- SMARTHOST_USER
- SMARTHOST_PASSWORD
volumes:
- /etc/postfix/main.cf:/etc/postfix/main.cf
ports:
- 25:25
然后，您可以使用smtp作为您的邮件主机/传输和来自环境的用户/通行证。
我不是容器专家，但如果我理解正确，您正在尝试访问容器中的127.0.0.1(php.ini localhost config解析为127.0.0.1)，我认为这不是主机地址，而是指向容器内部。
找出php.ini中的主机IP和更改：
[mail function]
SMTP = host_address
smtp_port = 25
我找到的最好的解决方案是安装msmtp并将以下内容添加到php.ini文件中。
sendmail_path = /usr/bin/msmtp -t --host host.docker.internal --from php@docker
现在您的邮件将由您的邮件服务器(smpt4dev或mailh)接收
