Cannot send email from Evolution - "Invalid or missing message signature"

[zarandya]

I am no longer able to send email from Evolution to non-Protonmail recipients. I am getting the following messages:

Downgrading Evolution and/or Hydroxide did not make the error go away, so it is probably a change in the Protonmail API. Another device running Hydroxide+FairEmail still works though.

I have not set up any signing keys in Evolution or Protonmail.

Same issue for me with git sendemail using hydroxide.

EDIT: it suddenly started working again for me this morning with git sendemail... so temporary upstream issue at Proton?

[zarandya]

nope, evolution still doesn't work

Any news from this? It started happening again for me and, looking at the logs, I found the POST returned to be:

5001 "Missing x-pm-appversion header" which seems to me like protonmail is now checking for a specific header from their bridge apps...

this is happening to me now.. trying to sent a git patch using git sendmail O_O
