everybody. I've been looking for the mistake in a few days now..

When i want to connect my Webmail with my E-Mail Server via Imap/Smtp, i got this error: "Authentification failed". When you need more Informations, please ask. Can you guys find my config issue?

Kind regards.

Error message:

A few things - your ability to log in to webmail has nothing to do with Postfix or SMTP (that may be relevant for actually sending emails, nothing else)

You appear to assume webmail uses IMAP authentication (which is a reasonable but not guaranteed assumption)
You should get IMAP working and check it with a regular mail client like thunderbird or outlook. (Or use telnet and IMAP commands, but that's quite advanced) to check IMAP works.

Your current dovecot configuration appears to only use an SQL database to authenticate users You either need to change this behaviour or add the admin to the SQL database. (You can see this behaviour because the driver to check user and password in the config is SQL). You have not provided the SQL config file/etc/dovecot/dovecot-sql.conf but that file should tell you what database and fields need to be used.

Alternatively change the driver to use the system database as per https://wiki.dovecot.org/PasswordDatabase/PAM - note that this could decrease your systems security. You will also need to change your config to allow plaintext author to make this work.
