Well, that's interesting. Here is my /etc/network/interfaces:

There's nothing in /etc/network/interfaces.d/ . This is a stock Debian 11
install, so whatever's in this file hasn't been messed with. No mention of
eno1. However, it DOES come up. Any clues?
There's no such thing as a "stock install". There are many possible
installs, depending on which choices you make during the installation.
If your interface isn't defined in /e/n/i then the most likely place
it's being brought up is in Network-Manager. If it's not N-M then
perhaps someone has configured your system to use systemd-networkd,
but that's not enabled by default in Debian, so it's far less common.
How about "/etc/NetworkManager/system-connections/Wired connection 1"
(who comes up with these Windows filenames?):

[ipv6]

"Stock install" in this case means I just let the installer set up the
networking, etc. Since eno1 is the wired connection, I assume this is
where it gets set up. However, this doesn't really answer the question
of why eno1 apparently not ready when OpenSMTPd wants to start.
