Folks:

This may require someone who's familiar with OpenSMTPD. I have a machine
which does backups (buckaroo) and a desktop (yosemite) which is my main machine. When anacron kicks off the backup, it should create an email for
root to detail what happened. Buckaroo is headless, so I want that email to come to me at yosemite. (All this is on a LAN.)

I'm using OpenSMTPD on buckaroo to handle mail. Here's my config:

---
# $OpenBSD: smtpd.conf,v 1.10 2018/05/24 11:40:17 gilles Exp $

# This is the smtpd server system-wide configuration file.
# See smtpd.conf(5) for more information.

table aliases file:/etc/aliases
table secrets file:/etc/secrets

listen on localhost

action "relay" relay host smtp+notls://@yosemite.mars.lan:25 auth <secrets>

match from local for any action "relay"
---

If I send an email directly to paulf@yosemite.mars.lan from buckaroo, it arrives. That means this config can do what it's designed to do, basically. However, mails to "root" on buckaroo don't get to yosemite. They should, because my /etc/aliases table looks like this:

---
...
root paulf@yosemite.mars.lan
---

But it appears that OpenSMTPD doesn't consult this table unless explicitly instructed to. According to man smtpd.conf(5), you can tell it to scan
through aliases, but only on local delivery, not if the email is outbound.

So does anyone know how to make OpenSMTPD do alias conversions on outbound

Still out of my depth with OpenSMTPD, but... good ol' aliases,of sendmail
lore would have a colon after the "root" up there. The MTAs I know of
all have inherited that.

And... if your MTA distro came with a command "newaliases" try running
that. Many MTAs like to look things up in a hashed version of the textual
file.

There is a colon in my aliases file. I just omitted it in the email.

I see. Then I'm out of ideas (except that "newaliases" thing). Perhaps
your MTA has a log file where to find clues?

Cheers & good luck

I don't know anything about opensmtpd, but use exim4 where, to send
emails to other hosts on the LAN, AIUI you either need a DNS server
that can resolve the LAN addresses or, instead, a hubbed hosts file.

Cheers,
David.

What does this mean?

But it appears that OpenSMTPD doesn't consult this table unless explicitly instructed to. According to man smtpd.conf(5), you can tell it to scan through aliases, but only on local delivery, not if the email is outbound.

So does anyone know how to make OpenSMTPD do alias conversions on outbound mail? Or alternatively, is there a way to hack Debian so that mails
generated from root processes to go an offsite email rather than just root?

What is in the logs?

I am pretty sure you don't tell us whole truth.

Don't do that. Always use copy and paste to convey the contents of a configuration file. Murphy only know what else you inadvertently left
out or added.

Please try:

smtpctl update table aliases

...as root.

I had this command documented in my anisble recipe for OpenSMTPD.

# If you edit the file, you have to run "smtpctl update table aliases"
table aliases file:/etc/aliases
