Build a Simple MTA in GOLANG

Job ID: 33237085

Budget: €30 – €250 EUR

To improve the email transport from an old-style email client (webmail) to a new SMTP server (requiring STARTTLS), I need to change some connection values while processing the emails.

Currently, the mails are all sent to a single SMTP server to get forwarded to their destination. The current client does not support STARTTLS.
I will have to switch to another SMTP server, which requires STARTTLS, so I need to tweak the transport.
Please have a look at the uploaded picture and the uploaded readme about the intended process.
