My notifications is from “openproject@example.net” even that I changed the mail in the GUI and also in the /opt/openproject-ce/config/configuration.yml

default: rails_cache_store: <%= ENV.fetch('RAILS_CACHE_STORE') { :memcache }.to_sym %> session_store: <%= ENV.fetch('SESSION_STORE') { :cache_store }.to_sym %> email_delivery_method: sendmail smtp_address: smtprelay1.xxxxxxxxx.com smtp_port: 25 smtp_domain: xxxxxxxxxxxxxx.xx smtp_authentication: <%= ENV.fetch('SMTP_AUTHENTICATION') { :login }.to_sym %> smtp_user_name: <%= ENV['SMTP_USERNAME'] %> smtp_password: <%= ENV['SMTP_PASSWORD'] %> attachments_storage_path: <%= ENV.fetch('ATTACHMENTS_STORAGE_PATH') { "/var/db/_APP_NAME_/files" } %>

My smtprelay does not need an user name or password.

Thanks,
