I am trying to setup sogo for my small team. What I managed to do is to setup a leightweight ldap (lldap) and connect it to my sogo. Since the user basis is the same there as in my mail server, that is connected via IMAP, I can instantly read the mails in SOGo, which is quite nice. Whats not working is the SMTP. When I send an E-Mail, I get an auth error. In the SMTP log I see, that the AUTH plain does not send any user/pass parameter. How can I make SOGO do that? The goal is, that a user can simply send an email in their name over the external SMTP server. I do not want to burden myself to host a custom SMTP, since we already have the other one. S: <SMTP-Reply: code=220 line='kundenserver.de (mreue011) Nemesis ESMTP Service ready'> And this is my shortened and simplified configuration. I am open for any hint!     SOGoProfileURL = "mysql://sogo:foo@sogo-db:3306/sogo/sogo_user_profile";     OCSFolderInfoURL = "mysql://sogo:foo@sogo-db:3306/sogo/sogo_folder_info";     OCSSessionsFolderURL = "mysql://sogo:foo@sogo-db:3306/sogo/sogo_sessions_folder";     OCSEMailAlarmsFolderURL = "mysql://sogo:foo@sogo-db:3306/sogo/sogo_alarms_folder";
