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 🙂
Nah you can use ghetto smtp to relay incoming mail to a different port on your server if your ISP blocks incoming 25 and sendinblue (it’s changed names but my sendinblue config is still working) to send outgoing mail if they block outgoing 25. It’s less than ideal but doable for low volume private email servers.
This suggestion always amuses me.
“You can easily run a mail server! All you have to do is route all the mail through someone else’s mail server and bam, you’re running a mail server!”
I mean it’s not wrong, but it causes a case of the giggles.
