A simple SMTP mail server, a tiny but complete realization of smtp protocol.
- OS: only for Linux/Unix plantform
- Multithread: create a thread for each client's request
- Authentication: store username and passwd to a file
- Base64 encode and decode

git clone https://github.com/ibillxia/xsmtp.git
cd xsmtp
- Edit Config Set the user data storage directory:
vim conf.h
Set the variable data_dir to /home/YourName/data.
- Add files and user account
cd /home/YourName/
mkdir data
vim userinfo
#add two users in this file
#[email protected]
#[email protected]

sudo xsmtp
