RuntimeError

This happened during sending an email from Taranis-NG which implements envelope 2.1.1 in email publisher. Would upgrade to 2.2.0 fix this?

This won't help, no such thing was handled in there. I’ve been racking my brain trying to solve this bug but I'd really need the e-mail that should be sent. I have to step through it to say whether it is the error of envelope or the underlying python thing.

Even the log seems strange, take a look, it's a stack going down through Envelope to the python smtplib.py

...
File "/usr/local/lib/python3.13/smtplib.py", line 870, in sendmail
                   ~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^
    return self.getreply()
  File "/usr/local/lib/python3.13/smtplib.py", line 398, in getreply
    line = self.file.readline(_MAXLINE  1)

Then, the next line comes from Taranis-NG: sent = envelope.send().

Then, the next line come from envelope going again down to the python smtplib.py .

Can you gimme a sample, either here or privately?
