I am trying to send mails via Azure as lined out here.
I can successfully send mails manually via cURL and via python's sendmail.
The email-notify pipe (v.0.13.2) however fails, as it seems like the SMT server (smtp.azurecomm.net) does not support noop. The log with the debug mode enabled shows
reply: b'250 2.6.0 72a61f1a-199e-401d-b228-5dba15b0d9ee Queued mail for delivery\r\n'
reply: retcode (250); Msg: b'2.6.0 72a61f1a-199e-401d-b228-5dba15b0d9ee Queued mail for delivery'
data: (250, b'2.6.0 72a61f1a-199e-401d-b228-5dba15b0d9ee Queued mail for delivery')
send: 'noop\r\n'
reply: b'502 5.3.3 Command not implemented\r\n'
reply: retcode (502); Msg: b'5.3.3 Command not implemented'
send: 'quit\r\n'
✖ Failed to send email to <target>. : response (502, b'5.3.3 Command not implemented')

reply: retcode (221); Msg: b'2.0.0 Service closing transmission channel'
Any advice?
