I have an issue with a postfix install, version 3.5.17, in a email server with Debian 11, where when given an email with a list a recipients and if a recipient is not well written, like using uppercase letters or special characters like á or ñ, the email is bounced automatically for every recipient (even if it is in CC or BCC) in the list. I've checked the postfix configurations, in main.cf
, but seems not to be a configuration related to this behavior. What are the posible causes of this behavior and how to correct it to only bounce for the wrong recipient but to deliver normally for the rest of addresses?

You can change this behavior by adding the following directive in your postfix, main.cf configuration.
