On Sunday, August 22nd 2010 there will be a outage of the mailsystem from 13:00 to 17:00. The reason is the installation of a new SMTP system. I 'am migrating from Courier-MTA to Exim4, ultimately bringing some new features to the mail system like Sieve, greylisting and two-stage-spamassassin-checks.

Downtime is intended to be kept at a minimum and retrieval of mails through IMAP/Webmail will be unaffected. Incoming and outgoing mails will be delayed though.
