When asked for password through mail: do not react\!

This post is over 5 years old, it may be out of date.

Every so often our users receive phishing-mail, in which a prompt response with username and password is requested. C&CZ likes to stress *again* that it is not very wise to believe something just because is written in a letter or e-mail and that *no official institution* will ever ask you for your password, just like a bank never will ask you for your pincode for your bank account. If a naive user falls for this scheme, his account is normally soon thereafter misused to send spam, with the effect that our mailservers are included in blacklists, causing problems for all users.
