I managed today to use letsencrypt certificate for my mail-server as well. It was awesome easy.
i am using an ubuntu and have mail-server on the the same domain as my admin domain.
y.jru.me
so – i got a letsencrypt certificate for this domain and used it as well for dovecot and postfix.
main.cf / postfix
smtpd_tls_cert_file = /etc/letsencrypt/live/y.jru.me/fullchain.pem
smtpd_tls_key_file = /etc/letsencrypt/live/y.jru.me/privkey.pem
Wir haben bei unserem Neubau vor knapp 2 Jahren uns für das Türschließsystem Burg Wächter TSE 4000 entschieden.
Heute bin ich etwas enttäuscht. Ich möchte Ihnen gern erläutern warum:
P.S: Die Krönung ist dann – das die Burg-Waechter IT scheinbar nicht mal in der Lage ist den Mail-Server ordentlich zu konfigurieren:
Your message
Subject: TSE Home 4000 – Probleme
was not delivered to:
tse@burg-waechter.com
because:
Router: Unable to open mailbox file W-DOMINO01/SERVER/BURG-WAECHTER/DE mail.box: Remote system no longer responding
Aber wer auch Lotus Notes einsetzt ….
Na Mahlzeit…
This is a little reminder to myself on how-to get a CSV list out of an standard Active Directory/ldap:
[string] $ldapFilter = "(&(objectClass=User)(!(objectClass=Computer))(displayName=*, *)(telephonenumber=*))";
[string[]] $propLoad = @("displayname", "telephoneNumber");
[System.DirectoryServices.DirectoryEntry] $baseDn = New-Object "System.DirectoryServices.DirectoryEntry" "LDAP://ldap...";
[System.DirectoryServices.DirectorySearcher] $searcher = New-Object "System.DirectoryServices.DirectorySearcher" $baseDn, $ldapFilter, $propLoad, 2
$searcher.PageSize = [Int32]::MaxValue;
[System.DirectoryServices.SearchResult] $result = $null;
[string[]] $resultList = @();
foreach($result in $searcher.FindAll())
{
$resultList += $result.Properties["displayname"][0].ToString() + ";" + $result.Properties["telephonenumber"][0].ToString();
}
[System.IO.File]::WriteAllLines("C:\Temp\PhoneRF.CSV", $resultList, [System.Text.Encoding]::UTF8);
