It could have been me (your webmail watched)

For sending an email exposing Chinese government spin, Shi Tao is in the third year of a ten-year prison sentence, while his family endures relentless official harassment

I use webmail all the time, receiving something like 300 emails a day, sending probably 30 a day. Running a popular political gossip site means that the content of the emails often contains information which, if not an actual state secret, is something that people in the government would rather was not revealed. On a good day my website annoys Downing Street and the party spin machines. Annoys them immensely.
