Dec 23 21:02:45 mail journal[2340]: iredapd [127.0.0.1] RCPT, abuse@domain.org => abuse@alias.com -> postmaster@domain.org, REJECT Sender is not same as SMTP authenticate username [sasl_username=abuse@domain.org, sender=abuse@alias.com, client_name=mail.domain.org, reverse_client_name=mail.domain.org, helo=localhost, encryption_protocol=TLSv1.3, encryption_cipher=TLS_AES_256_GCM_SHA384, server_port=587, process_time=0.0035s]

when I add ALLOWED_LOGIN_MISMATCH_LIST_MEMBER = True in /opt/iredapd/settings.py, the user cannot send from the alias address.
if you add ALLOWED_LOGIN_MISMATCH_SENDERS = ['abuse@domain.org'] the user can send a letter from any domain. How to allow sending only from alias?
