Hi, I am not sure that this has a(n easy) solution or is even possible, but I thought that I would find out from experts because it has been difficult to search for the answer.
I have postfix running on both my home and office machines. I am able to send e-mail from my office machine (that uses my employer's mailhub, etc), but not from my home machine when using my office e-mail address as the sender's address. However, I am able to connect via ssh+vpn with 2FA to my office machine. My question is: can I set my home machine's postfix up such that I can send e-mail through the ssh tunnel to my office machine (sorry for my non-technical description). How do I do this, if possible? Many thanks again for your time in reading this, and thanks in advance for any suggestions! Best wishes, Ranjan
