Apparently I installed that thing in 2006 and I last updated it in 2016, then I quit updating it for some reason that I totally forgot. Probably laziness…
It’s been running for quite some time and we kind of forgot about it in the closet, until the SSH tunnel we use to get our mail outside our home stopped working because modern openssh clients refuse to use the antiquated key cipher I setup client machines with way back when any longer.
I just generated new keys with a more modern cipher that it understands (ecdsa-sha2-nistp256) and left it running. Because why not 🙂
Did you really only use it when you were home? If you used it outside the firewall then port 25 must have been open also.
I used to run my own server and this was in the early 90s. Then one day, perusing the logs I realized I was not smart enough on the security front to even attempt such a thing. It was quickly shut down and the MX record moved to an outsourced mail provider.

Very very aware.
So you had another mail server elsewhere that port forwarded port 25 via port 22 to your internal mail server’s port 25.
I take it that outside mail server was secure.
That’s an impressive setup.

How does the mail come in tho bro? Or is your mail server just a client machine?
Maybe its for communication between family members
Where is the mail server getting incoming mail from?
Stop nuking comments pussy
Who shit in your cheerios dude, unclench.
That’s not what a SSH is. A ssh tunnel only allows traffic after a successful SSH authentication.
