Improved user security features

We’ve just released two improvements to users security when reading their email.

• Common phishing
  techniques in emails are now automatically caught and the link to
  the offending site is blocked. Note that this cannot catch all
  possible forgeries/phishing attempts, so users should still act with
  caution when reading emails that they don’t explicitly trust, but
  this should help in many common cases.
• Some common virus emails that are forged to appear to come from
  FastMail administrators are now automatically blocked for all users
