Email Service


  • In the course of 2022, the MPCDF Email Service will no longer be available for non-MPCDF employees

Email Server

The MPCDF maintains an email server exclusively for MPCDF staff. Email addresses have the following format:

Configuration of an Email Client

Email is sent and delivered using a client/server architecture. Please configure as your SMTP and IMAP server. The SMTP protocol sends emails, while the IMAP protocol allows the receipt of emails.


  • Note that is only accessible from within the MPCDF network.

Only encrypted communication, using the SSL/TLS protocols, is supported. Therefore you must use the following ports:

  • SMTP port 465

  • IMAP port 993

The email server uses a certificate based on the root certificate of the Deutsche Telecom Root CA2. This root certificate is integrated in many operating systems and email clients. If this is not the case, the certificate can be downloaded from here.

More information on setting up and configuring an email client can be found here.

Using Webmail

If you cannot use your own email client, you may use Roundcube

Please enter your userID as “Username”.

Spam and Malware

Each email arriving from the outside is examined automatically by two different virus scanner programs. If a virus or other malware is found, the email is quarantined and a note is sent to the intended recipient instead.

Attachment blocking

Each email arriving from the outside or send from inside is checked for potentially dangerous attachments. A list of blocked file types could be found here.

Out of Office Replies

The out of office vacation function can be activated on the userspace. The email server will automatically reply to incoming messages to inform the sender that you are away from the office.

The mechanism keeps track to whom it already sent an out of office message. Out of office replies are only sent once per week per sender. Out of office replies are not sent to (correctly configured) mailing lists.
