自建sentry后，配置了邮件服务，但是还是收不到验证邮件？

Question

问题描述

我已经在config.yml中配置了邮件服务器

mail.backend: 'smtp'  # Use dummy if you want to disable email entirely
mail.host: 'smtp.exmail.qq.com'
mail.port: 587
mail.username: '×××××××'
mail.password: '×××××××'
mail.use-tls: true
# The email address to send on behalf of
mail.from: '××××××'

而且发送测试邮件，我也收到了

但是我在验证邮件部分，却一直收不到邮件

是我什么地方还没有配置吗？
看了一下smtp service的log

Answer 1

其实这个问题，在docker-compose.yml添加环境变量就好了：

version: '3.4'

x-defaults: &defaults
  restart: unless-stopped
  build: .
  depends_on:
    - redis
    - postgres
    - memcached
    - smtp

  environment:
    # Run `docker-compose run web config generate-secret-key`
    # to get the SENTRY_SECRET_KEY value.
    SENTRY_SECRET_KEY: '1o-sqivmbumzrgzyx@wgn3&9l2)xvxktgr+t-o9%9d0@=de&27'
    SENTRY_MEMCACHED_HOST: memcached
    SENTRY_REDIS_HOST: redis
    SENTRY_POSTGRES_HOST: postgres
    # 这里添加一下
    SENTRY_SERVER_EMAIL: 'your_username'
    SENTRY_EMAIL_HOST: 'smtp.exmail.qq.com'
    SENTRY_EMAIL_PORT: 587
    SENTRY_EMAIL_USER: 'your_username'
    SENTRY_EMAIL_PASSWORD: '********'
    SENTRY_EMAIL_USE_TLS: 'true'
    ....
    

我发现，发送验证邮件和异常的通知邮件，都是通过worker这个Service

以下答案不是最新的，但是体现了我解决的过程

我昨天认真的看了一下日志，发现验证邮件是通过smtp这个Service发送的，然后我看了它的日志：

smtp_1       |   290 LOG: MAIN
smtp_1       |   290   H=gmail-smtp-in.l.google.com [2404:6800:4008:c07::1b] Cannot assign requested address
smtp_1       |   290 Connecting to gmail-smtp-in.l.google.com [108.177.97.26]:25 ... failed: Connection timed out (timeout=5m)
smtp_1       |   290 LOG: MAIN
smtp_1       |   290   H=gmail-smtp-in.l.google.com [108.177.97.26] Connection timed out
smtp_1       |   290 Connecting to alt1.gmail-smtp-in.l.google.com [2607:f8b0:4003:c19::1a]:25 ... failed: Cannot assign requested address

发现这个服务并没有去使用config.yml中的配置，因为我配置的smtp server是腾讯的smtp.exmail.qq.com，端口为587
我已经在web这个Service添加了挂载了

web:
    <<: *defaults
    ports:
      - '127.0.0.1:9000:9000'
    volumes:
      - ./config.yml:/etc/sentry/config.yml

web这个Service，也就是使用的web界面，是正确读取了配置了，那说明问题在于smtp这个Service。
我看了一下它的镜像，是使用tianon/exim4这个镜像，它的入口shell

#!/bin/bash
set -e

opts=(
    dc_local_interfaces '0.0.0.0 ; ::0'
    dc_other_hostnames ''
    dc_relay_nets '0.0.0.0/0'
)

if [ "$GMAIL_USER" -a "$GMAIL_PASSWORD" ]; then
    # see https://wiki.debian.org/GmailAndExim4
    opts+=(
        dc_eximconfig_configtype 'smarthost'
        dc_smarthost 'smtp.gmail.com::587'
    )
    echo "*.google.com:$GMAIL_USER:$GMAIL_PASSWORD" > /etc/exim4/passwd.client
else
    opts+=(
        dc_eximconfig_configtype 'internet'
    )
fi

set-exim4-update-conf "${opts[@]}"

if [ "$(id -u)" = '0' ]; then
    mkdir -p /var/spool/exim4 /var/log/exim4 || :
    chown -R Debian-exim:Debian-exim /var/spool/exim4 /var/log/exim4 || :
fi

exec "$@"

查询了一下，这个镜像是使用debian上的Exim4来发送邮件的，它的一些配置

dc_eximconfig_configtype='internet'
dc_other_hostnames=''
dc_local_interfaces='127.0.0.1'
dc_readhost=''
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost=''
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname=''
dc_mailname_in_oh='true'
dc_localdelivery='maildir_home'

dc_eximconfig_configtype这个参数，写了internet的话，smtp是自动去查询出来的，所以smtp server的日志里，才会去使用google的smtp server，如果你要写固定的配置的话，你应该把dc_eximconfig_configtype协成smarthost，然后配置dc_smarthost为你的smtp server，注意里头是两个冒号，另外还需要把对应的账号密码写到/etc/exim4/passwd.client这个口令文件中，如

*.google.com:your_user_name:your_password

.google.com之前的只是一个通配，其实这些事从这段shell也看出来了

if [ "$GMAIL_USER" -a "$GMAIL_PASSWORD" ]; then
    # see https://wiki.debian.org/GmailAndExim4
    opts+=(
        dc_eximconfig_configtype 'smarthost'
        dc_smarthost 'smtp.gmail.com::587'
    )
    echo "*.google.com:$GMAIL_USER:$GMAIL_PASSWORD" > /etc/exim4/passwd.client
else

所有，我目前临时解决了一下，就是把这个docker-entrypoint.sh给改了，挂载到容器里去，记得要赋x权限，
最好的方法应该是把这个镜像改改，能识别一下环境变量

看下sentry系统监控内有没有报错

Answer 3

没有验证邮箱的时候也可以接收邮件通知，具体配置看这里
