SmtpTelegramRelay is an SMTP server that relays all received emails to the specified telegram bot subscriber. Works as a windows service or as a standalone application. Completely written in C#.

Specify your telegram bot token and chatId in SmtpTelegramRelay.exe.config

  <telegramSettings token="SPECIFY THERE TELEGRAM BOT TOKEN" chatId="SPECIFY THERE TELEGRAM CHATID" />`
  <smtpSettings port="25" />

Start SMTP Telegram Relay as a service or as a standalone application:

• SmtpTelegramRelay.exe without parameters runs SMTP Telegram Relay as a standalone application.
• SmtpTelegramRelay.exe install installs SMTP Telegram Relay as a service. Don't forgive to manually start the service after installation.
• SmtpTelegramRelay.exe uninstall uninstalls the SMTP Telegram Relay service.

Send a test email through your SMTP Telegram Relay. Use localhost as an SMTP server address, 25 as a port and no authentifiacation or basic authentification method with fake username and password.
