Question on pf in the context of opensmtpd
Hi all,
I was thinking about my email setup that I have running right now where I am hosting my own mail server on a residential ISP (which blocks port 25 across the board. My solution was to stand up another server on a DigitalOcean VM that ran opensmtpd and relayed that mail to a high-numbered port on my server inside of the residential ISP network. My question is this - did I massively over-engineer this? Could I have simply used a pf rule on the DigitalOcean VM to redirect port 25 traffic to my other host on a different port? Or would that not be a proper use of pf? Thanks in advance. I'm really curious here if I could simplify my solution. |
