How to send a message on behalf of another user in mutt?

Question

Mail server

Hello.
I have a domain - mydomain.com. I need to send a message on behalf of another domain - other.net. The DNS for the other.net domain is configured with an SPF record pointing to mydomain.com.

v = spf1 include: other.net include: mydomain.com -all

Mail server 1.3.2 MARIADB edition.

For sending I use the Mutt client.
Here are his settings

set ssl_starttls = yes
set ssl_force_tls = yes
set ssl_use_sslv3 = yes
set timeout = 60
set smtp_authenticators = "login"
set smtp_url = "smtp: //[email protected]@mail.bessey.ru: 587"

set realname = "Noreplay"
set from = "[email protected]"
set smtp_pass = "[email protected]$$W0rd"
set copy = no

when sending a message i get this error
554 5.7.1 : recipient address rejected: sender does not match username for SMTP authentication

in forum thread - https://forum.iredmail.org/topic11192-smtp-error.html
i found information, that I need to edit the setting in the file - /opt/iredapd/settings.py, add the required address to the setting ALLOWED_LOGIN_MISMATCH_SENDERS = ['your_sasl_auth_username'] and restart the service

Unfortunately, this did not help. Please tell me how to send a message on behalf of another domain in mutt.
