I am trying to replace Sendmail with OpenSMTPd
<https://www.opensmtpd.org/>, which I like very much. It is sending
messages to remote mail servers successfully now. Email to local
addresses is also accepted, but not delivered to them — causing routing
loop:

My Cyrus <https://www.cyrusimap.org/> 3.8.5_1 on FreeBSD 14.3-RELEASE is
working, active, and accepted mail from Sendmail on the following
socket, set in cyrus.conf
<https://man.freebsd.org/cgi/man.cgi?query=cyrus.conf&sektion=5>:
||action "cyrus" lmtp /var/cyrus/socket/lmtp||
I appended this string with aliases in smtpd.conf
<https://man.openbsd.org/smtpd.conf>:
|action "cyrus" lmtp "/var/cyrus/socket/lmtp" alias <aliases>|
Since I sent this message to ‹postmaster›, and smtpd
<https://man.openbsd.org/smtpd> overwrote it with my real mail name, I
have to assume that /etc/mail/aliases table (inherited from Sendmail)
acts properly. Where could my settings error be causing the delivery loop?
I have made quite simple smtpd.conf(5)
<https://man.freebsd.org/cgi/man.cgi?query=smtpd.conf&sektion=5&manpath=freebsd-release-ports>

I have redirected all Sendmail functions to OpenSMTPd in mailer.conf
<https://man.freebsd.org/cgi/man.cgi?query=mailer.conf&sektion=5>
according to OpenBSD manual <https://man.openbsd.org/mailer.conf.5>.
sendmail /usr/local/sbin/smtpctl
send-mail /usr/local/sbin/smtpctl
mailq /usr/local/sbin/smtpctl
makemap /usr/local/sbin/smtpctl
newaliases /usr/local/sbin/smtpctl
I have also tried appending aliases(5)
<https://man.freebsd.org/cgi/man.cgi?query=aliases&sektion=5&manpath=freebsd-release-ports>
with Cyrus commands for clarity — no effect:
# FreeBSD Handbook: Mail: Procmail example:
# procmail: "|/usr/local/bin/procmail"
#
procmail: "|/var/cyrus/proc"
lmtp: "|/usr/local/cyrus/libexec/master"
lmtpd: "|/usr/local/cyrus/libexec/lmtpd"
lmtpunix: "|/var/cyrus/socket/lmtp"
Do any of you have some experience of LMTP on the same localhost? How to
teach MTA to communicate with MDA? Sorry, I could not find an
appropriate guide nor examples online.
