Communication Applications and Services
The objective of this activity is the provision of supported communication applications and services, currently email, PC file services, remote installation services as well as videoconferencing services and support of PC/workstation integration into JuNet. The main tasks are the operation, maintenance, and - if necessary - upgrading of supported applications as well as the analysis of the applicability and implementation of new services and applications.
Mail Services
JSC operates the central mail services including a central mail store, POP/IMAP mail access and SMTP mail forwarding. A mail virus scanner is operating on the central SMTP-Relay, cleaning infected messages at the entrance. To enhance security while accessing mail, clients in external networks are only granted access in an encrypted way based on ssl server certificates issued by the
FZJ Certificate Authority
(CA). Authenticity, integrity and confidentiality of email content can
be ensured by using user certificates, that are also issued by
FZJ-CA. A number of precautions are taken against unsolicited mail,
using the corresponding features of the SMTP server software. Backup
is provided for the most important services.
