在树莓派上安装和配置sendmail，搭建自己的邮件服务器

对于绑定自定义域名的邮箱，需要在域名解析里面增加mx记录，注意：记录值要填写已经解析过的地址，具体如下：

安装sendmail

sudo apt install -y install sendmail sendmail-cf

sendmail的smtp认证配置（不需要认证的可滤过）

设置sendmail服务的网络访问权限

DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl 

改为

DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')dnl 

生成sendmail配置文件

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf  #需在root权限下

添加域名

sudo nano /etc/mail/local-host-names
#添加 buryin.com

修改submit.cf文件

sudo nano /etc/mail/submit.cf

找到行 #Dj$w.Foo.COM，修改为

Djburyin.com

重启服务使能已配置参数

sudo service sendmail restart

测试一下邮件发送

echo “这是树莓派的sendmail测试” | mail -s 测试 up@up.day

其它可参数配置

centos安装sendmail服务及设置【亲测好用！】_Gavin Matthew的博客-CSDN博客_centos sendmail

sudo apt install dnsutils -y

为满足树莓派爱好者使用最新的高速编译工具，特别编译了codon，下载解压安装即可使用

安装后即可直接使用，比如编译fib.py：

codon build -release -exe fib.py

以打包codon为例
mkdir codon && cd codon
mkdir DEBIAN usr && cd usr && mkdir bin
cd DEBIAN
nano control


Package: codon
Version: 1.0.0
Architecture: arm64
Maintainer: jack
Secion: utils
Priority: optional
Installed_Size: #可以空白
Description: codon package
#此处要空一行

sudo dpkg -b codon
dpkg-name codon.deb #改名
sudo dpkg -i codon_1.0.0_arm64.deb  #安装
sudo dpkg -r codon #卸载,或者sudo dpkg -P codon

注意：
打包过程中，执行文件放入bin目录，usr的lib目录下放入so文件，同时在usr下拷贝stdlib目录

作为目前地表最强的python编译器，codon将python的执行速度提升了10-100倍并提供本地可执行二进制代码，遗憾的是官方并未照顾到广大树莓派爱好者的感受，未提供Raspberry OS环境下的执行程序，这里我从源码做了编译，提供给大家使用

sudo ./codon build -release -exe x.py

编译需要大量的交换空间，否则容易出错，因此先增加交换空间

sudo dd if=/dev/zero of=/swapfile bs=1G count=6
#count的大小就是增加的swap空间的大小，1G是块大小为1G，所以空间大小是bs*count=6G
sudo mkswap /swapfile  #把刚才空间格式化成swap格式
su
chmod 0600 /swapfile  
sudo swapon /swapfile  #使用刚才创建的swap空间

sudo pip install Ninja --break-system-packages
sudo apt install cmake

git clone --depth 1 -b codon https://github.com/exaloop/llvm-project
cmake -S llvm-project/llvm -B llvm-project/build -G Ninja \
    -DCMAKE_BUILD_TYPE=Release \
    -DLLVM_INCLUDE_TESTS=OFF \
    -DLLVM_ENABLE_RTTI=ON \
    -DLLVM_ENABLE_ZLIB=OFF \
    -DLLVM_ENABLE_TERMINFO=OFF \
    -DLLVM_TARGETS_TO_BUILD=all
cmake --build llvm-project/build -j4
cmake --install llvm-project/build

sudo apt-get install clang

cd llvm-project
cd llvm

sudo su

cmake -S . -B build -G Ninja \
    -DCMAKE_BUILD_TYPE=Release \
    -DLLVM_DIR=$(llvm-config --cmakedir) \
    -DCMAKE_C_COMPILER=clang \
    -DCMAKE_CXX_COMPILER=clang++
cmake --build build --config Release
cmake --install build --prefix=install

编译完成，释放临时增加的交换空间

swapoff -a
