Can you at least provide server logs? Also steps to reproduce.

Also, clarify the problem you are having. I made a guess that maddy is not sending the message body to remote servers, but that does not seem to be the case, at least in the basic scenario shown below.

SMTP session with maddy Submission endpoint

``` EHLO localhost AUTH PLAIN AHhpYW9iYWlzaHVAaHlhaG0uY29tAHRlc3Q= MAIL FROM: RCPT TO: DATA Content-Transfer-Encoding: base64 Content-Type: text/plain; charset="utf-8" Date: Fri, 6 Mar 2020 07:29:44 +0000 From: xiaobaishu@hyahm.com Message-Id: <51e85c99-12ca-442f-b686-c7c05344e838@smtp.hyahm.com> Mime-Version: 1.0 Received: by smtp.hyahm.com (envelope-sender ) with ESMTPS id a95fe02b; Fri, 06 Mar 2020 15:29:44 +0800 Subject: =?utf-8?b?6aqM6K+B5L2g55qE55S15a2Q6YKu566x5Zyw5Z2A?= bWF5YmUgeW91IGNhbiBub3Qgc2VlIHRoaXMgbWVzc2FnZSE= . QUIT ```

Received by the remote server

submission: DATA error  {"modifier":"submission_prepare","msg_id":"5121835e","reason":"Message does not contains a From header field","smtp_code":554,"smtp_enchcode":"5.6.0","smtp_msg":"Message does not contains a From header field"}

I am unable to reproduce that error message. Message generated by your client code definitely contains a From field.

What are these messages? Did you modify maddy source? If so, I am unable to provide any assistance without knowing about changes made.

Solved. thanks
