based SMTP relay/proxy server that accepts mail via SMTP\nand forwards it directly to another SMTP server.\n\n\n## Why another SMTP server?\n\nOutgoing mails are usually send via SMTP to an MTA (Mail Transfer Agent)\nwhich is one of Postfix, Exim, Sendmail or OpenSMTPD on UNIX/Linux in most\ncases. You really don't want to setup and maintain any of those full blown\nkitchensinks yourself because they are complex, fragile and hard to\nconfigure.\n\nMy use case is simple. I need to send automatically generated mails from\ncron via msmtp/sSMTP/dma, mails from various services and network printers\nvia a remote SMTP server without giving away my mail credentials to each\ndevice which produces mail.\n\n\n## Main features\n\n* Simple configuration with ini file .env file or environment variables\n* Supports SMTPS/TLS (465), STARTTLS (587) and unencrypted SMTP (25)\n* Checks for sender, receiver, client IP\n* Authentication support with file (LOGIN, PLAIN)\n* Enforce encryption for authentication\n* Forwards all mail to a smarthost (any SMTP server)\n* Small codebase\n* IPv6 support\n* Aliases support (dynamic reload when alias file changes)","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdecke%2Fsmtprelay","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdecke%2Fsmtprelay","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdecke%2Fsmtprelay/lists"}
