[BUG] nextcloud not using AUTH command even when "Authentication required" checked

[zen0x90]

Steps to reproduce

1. Install and configure your own mail server (ex: postfix)
2. Enable secure SMTP by activating submission (port 587) (authentication required)
3. Execute a test email with nextcloud (in settings)

Expected behaviour

Receive the test email.

Actual behaviour

Jun 24 00:59:35 mail postfix/submission/smtpd[20965]: NOQUEUE: reject: RCPT from some.domain.org[1.2.3.4]: 554 5.7.1 <some.domain.org[1.2.3.4]>: Client host rejected: Access denied; from=[email protected] to=[email protected] proto=ESMTP helo=<something.net>

It means nextcloud did a RCPT command before AUTH. In nextcloud settings you can configure your SMTP settings with "Authentication required" (checkbox). I did it but the error persist. I didn't check into the source code but it seems its a nextcloud bug.

Hi @zen0x90,

Nextcloud mail settings are handled by the Nextcloud server component, so please file an issue at https://github.com/nextcloud/server/issues/new

Thanks!
