1 week ago I do some debug. Enter in the container shell and explore postfix configuration. This is how "/etc/postfix/main.cf" is created (only the final part)
inet_protocols = ipv4 meta_directory = /etc/postfix shlib_directory = /usr/lib/postfix mydestination = relay_domains = header_size_limit = 4096000 smtpd_delay_reject = yes smtpd_helo_required = yes smtpd_client_restrictions = permit_mynetworks,reject smtpd_helo_restrictions = permit_mynetworks,reject_invalid_helo_hostname,permit smtpd_sender_restrictions = permit_mynetworks,reject relayhost = smtp.office365.com:587 smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt smtp_sasl_auth_enable = yes smtp_sasl_password_maps = lmdb:/etc/postfix/sasl_passwd smtp_sasl_security_options = smtp_sasl_tls_security_options = noanonymous smtp_sasl_mechanism_filter = xoauth2 smtp_tls_session_cache_database = lmdb:${data_directory}/smtp_scache message_size_limit = 0 myhostname = mail01 mynetworks = 127.0.0.0/8,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16 smtp_tls_security_level = encrypt
I read this page where there are some suggestion for configure postfix with oauth2, and merge with our config: https://mmogilvi.users.sourceforge.net/software/oauthbearer.html In our config:
- seems that "smtp_sasl_mechanism_filter" is setted on xoauth2
- try cat "/etc/postfix/sasl_passwd" and here is the output: smtp.office365.com:587 username@userdomain.it:/var/spool/postfix/xoauth2-tokens/username@userdomain.it
- ... i try cat the file "/var/spool/postfix/xoauth2-tokens/username@userdomain.it" but the file not exists.
Can be this the problem? I try create the file myself, but i not know exactly what the file must contain.
Thanks. Mauro.
Hi. Thanks for this project. Run boky/postfix:4.3.0-alpine on an Alpine 3.20 host, try relay to Microsoft 365, with OAUTH2, i receive this error:

Try add to host libsasl (apk add cyrus-sasl) but not know if i'm in the right direction and/or if what i try add to the host is correct. But the docker image not have all it need for run?
Here my docker-compose.yml
_name: postfix-docker services: postfix: restart: unless-stopped container_name: postfix environment:
Thanks. Mauro.
