dovecot: Search intlMailAddr for aliases in LDAP #317

Closed fredericmoulins closed 4 years ago

This change makes the aliases working on buster.

However, this configuration was not required on stretch. On buster, when the dovecot-lmtp gets the email for delivery, it considers it for the alias (eg log dovecot: auth: Debug: master in: USER#0112#011ada.lovelace@[…]) whereas on stretch it considers it for the already resolved user (eg ada@). I cannot see in the logs before dovecot-lmtp takes over where it would be different. The postfix ldap-aliases seem to do the work and resolve the alias ok.

The check-utf8-email.yml in tests is sending to an alias.

If you think this shouldn't be needed and can find a better fix in the integration between postfix and dovecot, it would be welcome.

Luckily, users won't be able to authenticate using utf8 characters, since auth_username_chars is set.
