Error: transaction failed: message doesn't contain a body part

[mdlaat]

Thank you for this project.

I seem to be unable to send an email using hydroxide, it always gives me the erorr:
554 5.0.0 Error: transaction failed: message doesn't contain a body part

When entering debug, I do see the body in the smtp session, a >> POST /api/messages, and a json with the body, but below that:

<< POST /api/messages
2024/11/24 20:07:24 &struct { protonmail.resp; Message *protonmail.Message }{resp:protonmail.resp{Code:1000, RawAPIError:(*protonmail.RawAPIError)(nil)}, Message:(*protonmail.Message)(0x2600000)}
554 5.0.0 Error: transaction failed: message doesn't contain a body part

The message is saved in the draft folders, but indeed without a body part.

What am I missing?
Thank you.

same here, but the message is:

554 5.0.0 Error: transaction failed: unknown sender address

Note

for me it's resolved: the email address used in hydroxide differed from the one at mail.proton.me in case: [email protected] != [email protected]

@JeromeSchmied I'm sorry, but you experienced a totally different error (and message). I guess you had better created your own issue. Glad it is working for you now.

My original problem stays. If someone can help, please do! Thank you.

well, can be possible, I'd have thought it was the same, according to the error number 554 5.0.0 Error: ...

isn't it so?

554 is a generic SMTP errorcode
