Horde webmail again appeared to be misused for sending spam. This could happen because a naive user gave the Science password to phishers/spammers. After first stopping horde, early Friday morning we disabled the account of the naive user and restarted horde. Saturday morning it appeared that this short spam-outbreak had caused administrators of hotmail.com to add our mail server to their blacklist. Therefore we switched the IP-number of this mail server Saturday morning.
