1 mu4e收发邮件

前言作为emacs的忠实用户,一直想把emacs配置成自己的邮件客户端.总是被繁琐的配置流程吓退了.直到最近看到一篇关于使用mu4e收发邮件的文章之后才行动起来,最终使用效果深感欣慰.总体来说解决了如何获取和发送邮件,如何管理邮件以及如何做界面展示.mu是基于maildir类型的邮件索引和客户端.mu4e是基于mu为emacs开发的客户界面. offlineimap则是基于imap协议的邮件获取客户端.三者搭配起来即可实现emacs邮件客户端.

软件安装和配置

offlineimap mac下直接使用brew命令即可安装最新版本的offlineimap.

brew install offlineimap

新建offlineimap的配置文件~/.offlineimaprc.配置好账户信息.出于安全考虑,最好不要在.offlineimaprc中填写明文密码.所以采用remotepasseval + .offlineimap.py + gpg的方式对口令进行加密.

[general]
accounts = xxxx
maxsyncaccounts = 3
pythonfile = ~/.offlineimap.py

[Account xxxx]
localrepository = LocalCxs
remoterepository = RemoteCxs

[Repository LocalCxs]
type = Maildir
localfolders = ~/mail

[Repository RemoteCxs]
type = IMAP
remotehost = imap.163.com
remoteuser = xxxx@163.com
remotepasseval = get_password_emacs("imap.163.com", "xxxx@163.com", 993)
ssl = yes
sslcacertfile = /usr/local/etc/openssl/cert.pem
nametrans = lambda foldername: foldername.decode('imap4-utf-7').encode('utf-8')
folderfilter = lambda foldername: foldername in ['Trash','Sent Items', 'Advertisement', 'INBOX', 'Junk E-mail']
maxconnections = 2
realdelete = yes

mu 使用brew命令安装me客户端.mu4e配套代码.

brew install mu --with-emacs

提示configure: error: Package requirements (glib-sharp-2.0 >= 2.4.0) were not met. 需要下载mono安装.

brew instal mono

使用gpg配置密码,避免密码明文写入. 首先安装gpg.

brew install gpg
gpg

使用gpg –full-gen-key命令生成密钥.

gpg --symmetric --cipher-algo AES256 .authinfo

配置.offlineimap.py文件.

#!/usr/bin/python
import re, os


def get_password_emacs(machine, login, port):
    s = "machine %s login %s port %s password ([^ ]*)\n" % (machine, login,
                                                            port)
    p = re.compile(s)
    authinfo = os.popen(
        "gpg -dq --batch --passphrase your_password ~/.authinfo.gpg").read()
    return p.search(authinfo).group(1)

mu4e

emacs配置我使用的是spacemacs,所以参考了email layer的部分设置.首先在中启用layer.

遗留问题
1. 需要完美解决fetch命令乱码问题.
