Mailservice

A simple self-hosted email sending HTTP API service using SMTP.

Why?

• Somehow the SMTP connections are blocked by ISP or the SMTP server, but a third server works.
• Centerized email sending configuration.

Configuration

Edit appsettings.json, add STMP account configurations:

{
"Urls": "http://127.0.0.1:8080",
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"AllowedHosts": "*",
"Mail": {
"Accounts": [
{
"Token": "should_be_random_generated",
"From": "sender@example.com",

"Host": "smtp.exmail.qq.com",
"Port": 465,
