I'm routing SMTP through a proxy in a container.
I can confirm email is sent when not routed through proxy.
But when i route through proxy, i see the following logs which are sent in sequence, after 30s of triggering the email send:
Error sending e-mail <email test>: timeout occured
send RSET
recv: 220 smtp.mymail.com ESMTP ready
send QUIT
recv: 250 2.0.0 OK
Any clue what could be going wrong?
