    On Ubuntu is /etc/postfix/sasl and not /usr/lib64/sasl2. Please correct your article.

    Hello @Tara,

    Thank you for the notice. This article is devoted to the error:

    mail.example.com postfix/smtpd[17318]: warning: SASL authentication failure: realm changed: authentication aborted

    In such case, Dovecot restart is not required.
