No luck. Although I redirected LMTP option from alias to virtual:

match !from local for domain <domains> action "cyrus"
match from local for local action "cyrus"
SMTP now attempts to deliver alias email to itself over MTA instead of

Would you mind sharing the contents of your <virtuals> table here? (you
can omit some emails if you need to)
Otherwise, I suggest you look at trace and debug options in man smtpctl,
which can help debug these kinds of issues.
I think I remember having the "Mailing list expansion problem" error
when I didn’t add lmtp-delivery (just a user on my system, used by
OpenSMTPD to deliver messages over LMTP) as an alias of “terminal” email
addresses.
In my case, it looks something like this:
[email protected] lmtp-delivery
[email protected] [email protected]
[email protected] [email protected]
and emails to [email protected] or [email protected] should deliver
with rcpt=<[email protected]> user=lmtp-delivery
