Re: expiring mail from root's Maildirs?
(Sorry about previous mail)

So dovecot cannot expire, reindex, clean, repair, etc root mail?
The mail is crontab mail that is sent out to users via mutt. What would be the "right” way to do this? (The cron tasks run as root because they are scanning system logs on behalf of certain users and those scans cannot be run as the user.)

Alias the local 'root' user to another account. This is best practice anyway...

For incoming mail the root user is aliased, but mail sent from cron via mutt is saved in root's home folder (was in /root/sent but I did get mutt to save it in /root/Maildir/.Sent/ instead.
I don't see anyway to change this, so I was hoping to expire the mail via doveadm.

outgoing mail should not be stored into root uid 0
but that is still not sure mutt does allow that
try imap: auth, and do stay away from filesystem as root user

in gentoo its
# cat /etc/mail/aliases
root: some-other-unix-login
or
root: some-other-email-with-snable-a
after this file is edited, issue a "newaliases && postfix reload" :)

Root has been aliased for decades. This has no impact on where and how mutt stores the mail it sends as root out of root’s crontab.

Can you use a set record= for root?

in muttrc you miss ~ or $(HOME)/something
root: some-other-unix-login

root user can read mail files for all unix users, thats your fail, maybe crontab miss $(HOME) where it matters, but if it have and you start mutt as root it does not help, and you see the problem in allow root to do too much
i dont know mutt in detail, but its a fail to start mutt as root
mutt must be started as some-other-unix-login
the remaining fail is then in that users muttrc

There seems to be a basic misunderstanding here.
root has a crontab. Part of that crontab parses some system log files (that only root has access to) for user data and generates an email in HTML. That email is sent via mutt because the basic mail commands could not send an HTML email properly.
Mutt stores that email in ~root, and the email comes from the root user because that is who wins the crontab.
The $HOME fro the user is /root/
i dont know mutt in detail, but its a fail to start mutt as root
Since the mail is generated out of root's cron, however the mail is sent, that process is going to be started by root.
mutt must be started as some-other-unix-login
See above.
the remaining fail is then in that users muttrc
There is nothing wrong in the root muttrc.

You could use tool like sudo or su to run mutt as non-root, instead of running it as root?

Maybe. Not sure if piping output in front to su will work, but I can certainly try it.

Thanks, that did work. Took a little, but no more sent mail in ~root.

What happens if you put the following in /root/.muttrc: Set record='/file/to/put/mail/in' ?

indeed possible, but this file will only be possible to read from root user
if it can be readed by other, its a security problem
