Finishing (or restarting) SOGo setup

We have been trying to set up a Groupwareserver running SOGo with the help of a freelancer. While the freelancer did a good job he just stopped working after some time and is not reachable anymore. The server is currently running SOGo on CentOS6, Apache, LDAP, Postfix and some more I can send you information about if requested. Right now our biggest problems are: Multidomain functionality is restricted (info@ [login to view URL] is also received by info@ [login to view URL]) Syncing in Outlook is restricted but has not always been. We think this may be a size limit. No working web based domain and account handling. (Lack of documentation for us to work with the server.) Your task would be to fix these problems. Alternatively a new setup would be possible. The system should run on a Virtual Server, hosted CentOS 6.x, Debian or Ubuntu (your choice) Apache preinstalled Otherwise clean setup Prerequisites: Apache configured for virtual hosts (4+ domains) SSL (no wildcard, certificates available) Database server (recommended by the SOGo guys: PostgreSQL 7.4+) LDAP server (recommended by the SOGo guys: Open LDAP 2.3.x+) SMTP server (recommended by the SOGo guys: Postfix 2.x) IMAP server (recommended by the SOGo guys: Cyrus IMAP server 2.3.x+) While the recommendations are not binding we’d like to stick to some standard, so well-known replacements are possible ;-) The usual protection against spam and viruses (e.g. AMaViS, ClamAV and SpamAssassin) Requirements: SOGo 2.15+ with MAPI and ActiveSync support, multi domain support (4+), centralized (webbased) domain and user configuration, authentication with LDAP (locally installed) Webaccess to Sogo on [login to view URL] We are willing to pay the following rates (negotiatable): 200€ for fixing our problems (listed above) 450€ for a new setup (with functionality listed above) 150€ for documentation that allows us to completely manage the server on our own (can be combined with both other cases) Additional requirements: Sufficient knowledge of English or German language to prevent communication errors You work in a quick pace (there is no time pressure, but we are not willing to wait for multiple months without any results again) If you do a good job there will be additional tasks in the future that we will of course pay for.
