GNU/Linux 下超酷又灵活的 Email 系统

2013年3月18日 (一) 11:18的版本

1 概述

简单地说就是：fetchmail 从邮件服务器取邮件到本地，经 procmail 过滤分捡后写入相应的 mailbox 文件，邮件客户端 Mutt 读取 mailbox 文件并与用户交互，使用 ssmtp 联系邮件服务器发邮件

fetchmail + procmail + Mutt + Exim4 的方案个人用了 7 年多，效率高，非常适合 Hacker/Geeker

近来发现 sSMTP 更好用，配置简单，风格和 fetchmail 类似，很自然地切到了 sSMTP

2 fetchmail 取邮件

fetchmail 的默认配置文件位于当前用户主目录下，即：$HOME/.fetchmailrc，没有可自己建一个

例如，我的 gmail 账户的 $HOME/.fetchmailrc 例子：

set postmaster "comcat"
set bouncemail
set no spambounce
set properties ""
set daemon 60

poll imap.gmail.com protocol IMAP port 993 auth password
	user "YOUR_GMAIL_USERNAME@gmail.com" there
	with password 'YOUR_GMAIL_PASSWD'
	is 'comcat' here options no fetchall keep ssl
	mda "/usr/bin/procmail -f %F -d %T"

3 procmail 分捡邮件

4 Mutt 读邮件

5 sSMTP 发邮件

$ sudo apt-get install ssmtp
$ vim /etc/ssmtp/ssmtp.conf

# The place where the mail goes. The actual machine name is required no 
# MX records are consulted. Commonly mailhosts are named mail.domain.com
Root=postmaster                        # Redirect mail for root@ to postmaster@

Mailhub=smtp.gmail.com:587             # TLS

AuthUser=YOUR_GMAIL_USERNAME           # Your DreamHost mail account
AuthPass=YOUR_GMAIL_PASSWORD           # The password for the mail account
UseTLS=YES                             # Secure connection (SSL/TLS)
UseSTARTTLS=YES

rewriteDomain=jackslab.org             # The host the mail appears to be coming from, seems like gmail can not be rewrited
hostname=jackslab.org                  # The name of this host

FromLineOverride=YES                   # Allow the user to specify their own From: address, seems like gmail is not allow
