2019-08-11: Switched to a new database backend

Today, the database servers has been migrated from a master-slave to a multi-master architecture (2 DB nodes + 1 quorum). Everything is working as expected, but maybe some adjustments have to be made in the next days. This shouldn't cause any issues, but who knows.

2019-07-31: XMPP - prosody to ejabberd migration

As first part of the long planned prosody migration I have finally started with the evaluation and testing of ejabberd. This will take some time, as there are some dismail specific things to take into account. If I do not come across any showstoppers, prosody will be migrated to ejabberd in a few weeks.

2019-07-24: fdns1 - some head scratching

2019-02-06: Support for TLS 1.0 and 1.1 is being discontinued in March 2019

dismail.de is going to drop support for TLS 1.0 and TLS 1.1 in March 2019 (IMAP and SMTP).
If you use outdated email clients or devices, please upgrade. If you are already using up-to-date email clients, you are most probably already using TLS 1.2.

2018-12-06: Prosody 0.11.1

Prosody 0.11.0 has been released on 2018-11-21 and a few days later Prosody 0.11.1

So why haven't I updated yet?

  1. The upgrade and migration of the mailsystem was and is very time consuming, but it's worth it.
    What we have now: load-balanced, georedundent systems which I could swear are also somehow hyperconverged ;)
  2. I am not an early adopter. The new software release needs testing even if there are no significant changes. The running Prosody version is at a local stable maximum with some known minor issues. The new release don't has any killer feature forcing me to upgrade in a hurry.
  3. The upgrade will be combined with a new server and a lot of testing and this needs time.
