Mail service of the BTU Cottbus - Senftenberg
BTU Email Service
The IT Services department operates BTU’s central email service. All users have 1 GiB of storage space available for incoming emails. For employees, the storage space can be increased within the limits of available capacity; currently, it is 4 GiB.
Email is particularly well-suited for exchanging manageable amounts of data. Messages can be sent to up to 100 recipients at once via the BTU mail servers. The maximum message size is 25 MB, including attachments. For larger files, please use appropriate services such as OwnCloud.
Setting Up Your Email Program
Most email programs support automatic setup. To do this, enter your BTU email address, the account type IMAP, and your BTU account credentials.
If you enter the information manually, use these server names:
- Inbox: Mailin.b-tu.de – Protocol IMAP
- Outbox: Mailout.b-tu.de
You can find your email address and other settings in the Account Portal under Email. To use the central email service, you need a BTU account.
Email Forwarding and Out-of-Office Message
In the Account Portal, under Email, you can set up forwarding to another mailbox. There, you can also enable an automatic out-of-office message and specify the message text.
Address Book Entry
An email address is stored for each user account in the BTU email address book. You can select your entry yourself in the Account Portal under Email. If you have a BTU user certificate, we recommend using the email address specified in it.
BTU Webmail
You can also manage your emails directly in your browser via BTU Webmail. In addition to email access, the web application offers address book management and a calendar feature.
Instructions on important basic settings for the calendar feature can be found in the download “Important / Useful Basic Settings for Horde Webmail”.
ORG Box
An ORG Box is a shared mailbox for departments, projects, and similar organizational units. Multiple authorized users can view and manage incoming emails via their BTU account. The ORG Box does not count toward the personal mailbox quota of the BTU account.
To access an ORG Box, you must subscribe to it in your email program.
Requesting an ORG Box and a Short Name
A short name is required to set up an ORG Box. This forms the first part of the email address, for example, kurzname@b-tu.de.
The Communications and Marketing department coordinates the assignment of short names to ensure that the BTU presents a unified image to the outside world. Information on namespaces and the assignment of a short name can be found on the Communications and Marketing department’s page.
Managing Owners and Users
Each ORG-Box has Owners and Users. Owners are the designated contacts responsible for the ORG-Box and can generally access it themselves.
There are two permission levels:
- Normal: Access to the ORG-Box without the ability to delete content.
- Advanced: Access to the ORG-Box with the additional ability to delete content.
Ownership must be requested from the Communications and Marketing department. Information on this can be found on the page on namespaces and short names.
Permissions for users are requested via the IKMZ ticket system. Only an owner of the relevant ORG-Box can submit a permission request.
Please include the short name of the ORG-Box, the names of the relevant individuals, and the desired permission level (Normal or Advanced) in the ticket.
