    Hi Sebastian,<br>
    <br>
    small hint out of Keycloak. Some email servers (eg gmail) allows you
    to use email addresses with unresolved part after + sign, like
    <a class="moz-txt-link-abbreviated" href="mailto:sebastian.olscher+something@traveltainment.de">sebastian.olscher+something@traveltainment.de</a>. Emails for this kind
    of address are delivered to "base" email
    <a class="moz-txt-link-abbreviated" href="mailto:sebastian.olscher@traveltainment.de">sebastian.olscher@traveltainment.de</a> then. This may help you create
    more accounts with different emails delivered to same person.<br>
    If your email server doesn't support this "dynamic" aliasing then it
    probably supports some "static" aliases defined by admin.<br>
    <br>
    Vl.<br>
