Mail server maintenance on Tue, March 27

Friday, March 23rd, 2018

Update 07:25 The migration is complete and our mail server is back online. Please let us know if you notice anything peculiar. This concludes our multi-step migration to the new mail server hardware

In order to finalize the upgrade of the D-PHYS mail server, we schedule a maintenance downtime on

Tuesday, March 27, between 06:30 and 08:00 in the morning

During that time it will not be possible to send or receive emails. In particular, incoming external emails will not be lost, but held on the sender’s side and will be delivered after the migration. Outgoing mail will be kept in your mail client until the connection is restored.

We will update this posting once the mail server is back online.

New location for mail filtering rules, forwarding and vacation auto-replies

After the migration, all mail-related settings will be consolidated into the Roundcube Webmail interface:

  • spam filtering rules (whitelist, blacklist)
  • forwarding of your emails to a different account
  • setting a vacation or out-of-office auto-reply message
  • defining rules to automatically file incoming mails into specific folders

This will make configuring your email settings easier and also give you more options than before (for example, the out-of-office auto-reply can now be configured to automatically terminate at the end of your absence).

Please refer to our readme for details on how to customize these settings in the future. Feel free to contact us if you have any questions.

The current settings of all active users have been converted and imported.

In technical terms we are migrating from procmail to sieve. In particular the hidden text file ~/.procmailrc in the user’s home folder will be ignored after the migration.

Mail server maintenance on Wed, Jan 24

Friday, January 19th, 2018

Update 07:25 Migration finished, welcome on the new mail server!

We schedule a maintenance downtime for the D-PHYS mail server on

Wednesday, January 24, between 07:00 and 08:00 in the morning

During this period, sending and receiving new emails will have interruptions, thereby delaying incoming and outgoing mails. In particular, incoming external emails will not be lost, but held on the sender’s side and will be delivered after the migration. Outgoing mail will be kept in your mail client until the connection is restored. The IMAP server will not be affected, so all email clients should have continuous access to the existing mailboxes.

This maintenance window will be used to migrate the first part of our mail server infrastructure to the latest version of the operating system and new hardware with fast SSD storage.

New location for SpamAssassin user preferences

We re-designed how our mail server is parsing the user’s configuration for the spam filtering. Currently one has to edit the hidden text file ~/.spamassassin/user_prefs in the home folder. Starting from next Wednesday the spam filtering rules can be edited more conveniently through the settings in the Webmail interface. This will allow users to easily

  • accept mail from a given sender and never mark it as spam (whitelist)
  • reject mail from a given sender and always mark it as spam (blacklist)
  • set the threshold score required for any message to be considered as spam

The existing user preferences have been parsed and all of the above settings have been imported into the new setup. The contents of ~/.spamassassin/ will be ignored after the migration. Please contact us if you have questions regarding your advanced SpamAssassin rules.

Short downtime for plempy, plompy and plumpy on Monday Aug 2

Tuesday, July 27th, 2010

On Monday, August 2nd, starting at 07:00, our terminal server / computation nodes plempy, plompy and plumpy will be moved into the water-cooled racks in the HIT server room. This will cause a downtime of said machines of about 30 min. If your thin client connects to plompy or if you’re performing calculations on plempy or plumpy, please make sure your data has been saved by Monday morning. After the move, the trio will enjoy the amenities of our most advanced server room that only another thunderstorm could disrupt.

Update Mon Aug 2 08:40 All servers have reached their final destination.

Service interruption

Friday, August 14th, 2009

Today at 07:04 a software upgrade of a core router performed by Informatikdienste caused an avalanche of errors in our server cluster, leading to an outage of printing and some other non-critical services. It took us till around 08:00 to get the systems back to normal. We apologize for any inconvenience.
