We had to shut down the D-PHYS mail server on short notice for replacing faulty hardware. Mail service should be back in the evening.
Mails sent to D-PHYS during the downtime will be on hold on the sending side.
Update, 19:30: The dust is settling. We're soon back to normal.
In order to perform system-level maintenance work, we schedule a maintenance downtime of the D-PHYS mail server today (Thursday, 2nd of July 2015) starting at 17:00. We expect the downtime to take about one hour.
During the downtime all mail services (sending mail, receiving mail, accessing mailboxes, webmail, etc.) will be unavailable. Mails sent to D-PHYS users during the downtime will be held back on the sending side and will be delivered after the downtime.
We will post an update as soon as mail services are back.
Update 19:30: Took a little bit longer than expected, but everything is back to normal now.
On Monday the public was made aware of a severe bug in OpenSSL, a cryptography library which is used as the core of many cryptographically secured IT services. Since the bug was in the Heartbeat extension it has been named "Heartbleed".
This bug allowed attackers to stealthily access parts of the memory used for cryptographic actions, i.e. it may include digital keys in use on servers or passwords transferred over encrypted connections.
If you used any password-protected D-PHYS web services or the D-PHYS mail server between 12th of December 2013 (or used the BackupPC web-interface since end of 2012) and Tuesday, the 8th of April 2014, there is a very small chance that your D-PHYS password and possibly other transmitted data may have been leaked to an attacker. We currently have no indication that this has actually happened on our servers.
To be safe, you might want to change the password of your D-PHYS account and any other account where the same password is used. See this Heise article for a discussion (in German) about whether you should change your password or not.
On Monday, November 16th, starting at 6pm we will migrate the D-PHYS IMAP and POP3 server to new hardware. Since this also includes converting all 450 GB of mailboxes on that server, the migration will take several hours. Update Tuesday, 2:50pm: Everything works again. The migration took about twice of the expected time due to some complications.
During the migration it will not be possible to access any of the D-PHYS e-mail services (receiving, sending or accessing your mails, webmail). E-mails sent to D-PHYS during the migration will be held back on the sender's e-mail servers.
After the migration you may need to resynchronise your e-mail client (e.g. Apple Mail or Mozilla Thunderbird) with the new IMAP server. Please read our mail server migration wiki page in case you use one of the e-mail clients mentioned above, use your own procmail filter rules or experience other problems after the migration.
