I have asked this question and am opening a new question as per SE policy.

The remote SMTP server can be connected to via its own 465 port.

However, I want to reach that server via a cloud server. This SE answer says, that both the sender and the receiver server communicates via port 25. But I want this:

Cloud server :--------> reach mail Server at port 465 :-----------------> Reach reciever mail address.

The second bridge is where both servers will communicate over port 25, that is clear. But in the first bridge, do I need port 465 open? Or is there a way for me to bypass port 465, yet send the EHLO and MAIL FROM commands to the mail server?

Thank you.

  • Do you have SSH access to the remote server? If so, I think you could use SSH port forwarding to do this. Look at the `-L` and `-R` options in SSH. – Spiff Mar 12 '23 at 04:05
  • i have ssh to cloud server., not to the mail server – Sean Mar 12 '23 at 05:01
