Installer and docs disagree on which port the incoming mail SMTP service lives on

[jdougan]

Docs [1] claim it will be installed on port 30025, the last default installs I did it (v303) put it on port 25.

I'll examine the installer behavior and then update the docs. My guess is this changed when we updated the installer to attempt to use 443 and such for production installs, but since inbound email is barely supported, nobody updated the docs for it.

Yeah, skimming through the install script it looks like there's some logic that tries to use port 25 if it's available.

Has anything about this been done in some other repo?

[ocdtrekkie]

Not yet. It's in my inbox still, but I've had a busy few weeks. The installer and the docs are all both in the main repo.

Hmmm, so there are two different things here, and I am unsure the best way to address it in docs:

1. The Sandstorm installer will set the config file to use port 25 for "full"/"as root" installs if it can.
2. If SMTP_LISTEN_PORT is not configured in the config, Sandstorm will use port 30025.

If you search for 30025, as above, you'll see comments about what Sandstorm does by default, but it's not what the installer does by default.
