linux下docker安装taiga Taiga是一款免费开源项目管理系统，比较适用于中小型敏捷项目管理，支持Scrum和kanban两种board 模板来跟踪项目的进度，同时还提供了丰富的第三方应用集成支持，如：视频会议功能与Talky.io和Appear.in的第三方服务结合；与基于Web的版本控制存储库（如GitHub和Bitbucket）进行交互；以及实时聊天工具slack集成等. 具体详细介绍，请参见https://taig... 阅读详情

1、SMTP邮件服务器搭建：

创建一个邮件目录，如/opt/email，并进入/opt/email

mkdir email

cd /opt/email

2、在当前目录下编辑main.cf

myhostname = mail.yourcompany.com
mydomain = yourcompany.com

myorigin = $mydomain
inet_interfaces = all

inet_protocols = ipv4
mynetworks = 127.0.0.0/8, [::1]/128

#此处决定你发送的邮件范围，多个用空格分开，比如要发送给111555555@qq.com则对应的域名为qq.com

relay_domains = tencent.com

smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination

3、编辑docker-compose文件

version: '3'

services:
mailserver:
    image: catatnight/postfix

    ports:
      - "0.0.0.0:9925:25"
    volumes:

     - ./main.cf:/etc/postfix/main.cf:ro
      - /disk1/send_email/mailserver/data:/var/m

thunderbird:
    image: jlesage/thunderbird
    ports:
      - "0.0.0.0:5800:5800"

    environment:
      - DISPLAY_WIDTH=1280
      - DISPLAY_HEIGHT=720

   volumes:
      - /disk1/send_email/thunderbird/data:/config

4、部署和拉起容器

docker-compose up -d

5、 telnet localhost 9925 验证是否部署成功

6、发送邮件测试：

import os
import smtplib
from email.mime.multipart import MIMEMultipart

from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders

import time
import logging

class SendEmail:
def __init__(self):
self.smtp_server = 'HOSTNAME'
self.port =PORT

def send(self,from_email,to_email_list,Cc,subject_title,content,filenamelist):

msg = MIMEMultipart()
msg['From'] = from_email

msg['To'] = ",".join(to_email_list)
msg['Subject'] = subject_title

if Cc:
msg['Cc'] = ', '.join(Cc)

msg.attach(MIMEText(content, 'plain'))

for each_file in filenamelist:
attachment = open(each_file, 'rb')

part = MIMEBase('application', 'octet-stream')
part.set_payload((attachment).read())

encoders.encode_base64(part)

part.add_header('Content-Disposition', "attachment; filename= " + os.path.basename(each_file))

msg.attach(part)

with smtplib.SMTP(self.smtp_server, self.port) as server:

server.sendmail(from_email,to_email_list, msg.as_string())
