At TBits.net, we are not using kolabHomeServer, but we modify the <br>
postfix configuration, so that postfix knows of the other server.<br>
We do it on both servers.<br>
<br>
/etc/postfix/transport<br>
should contain a line like:<br>
<a href="http://mydomain.com" rel="noreferrer" target="_blank">mydomain.com</a> smtp:[<a href="http://the_other_kolab.mycompany.com" rel="noreferrer" target="_blank">the_other_kolab.mycompany.com</a>]:25<br>
<br>
/etc/postfix/transportrecipient<br>
should contain a line like:<br>
@<a href="http://mydomain.com" rel="noreferrer" target="_blank">mydomain.com</a> OK<br>
<br>
then execute:<br>
postmap /etc/postfix/transport<br>
postmap /etc/postfix/transportrecipient<br>
systemctl reload postfix<br>
<br>
I hope this works for you!<br></blockquote><div><br></div><div>Hi Timotheus!</div><div><br></div><div>First of all, thanks a lot for your indication. </div><div><br></div><div>I tried modifying those files, but Kolab looks as if it is not taking the new configuration into account.</div><div><br></div><div>Maybe it's something about how ldap checks the needed files...I saw there is a <a href="http://transport_maps.cf">transport_maps.cf</a> inside /etc/postfix/ldap, but looks a bit cryptic to me.</div><div><br></div><div>I'm receiving something like this when trying to send emails to old server users, from new server users: </div><div><br></div><div><div>Nov 8 23:43:55 postino postfix/submission/smtpd[8136]: connect from localhost[::1]</div><div>Nov 8 23:43:56 postino postfix/submission/smtpd[8136]: NOQUEUE: reject: RCPT from localhost[::1]: 550 5.1.1 <<a href="mailto:old_server_user@mydomain.com.ar">old_server_user@mydomain.com.ar</a>>: Recipient address rejected: User unknown in local recipient table; from=<<a href="mailto:new_server_user@mydomain.com.ar">new_server_user@mydomain.com.ar</a>> to=<<a href="mailto:old_server_user@mydomain.com.ar">old_server_user@mydomain.com.ar</a>> proto=ESMTP helo=<<a href="http://postino.mydomain.com.ar">postino.mydomain.com.ar</a>></div><div>Nov 8 23:43:56 postino postfix/submission/smtpd[8136]: disconnect from localhost[::1]</div></div><div><br></div><div>Do you know if there is some other file I need to modify in order for that configuration (/etc/postfix/transport and /etc/postfix/transportrecipient) to be enabled?</div><div><br></div><div>Thanks again in advance, and best regards,</div><div><br></div><div>HeCSa.</div><div><br></div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
