[SAC] Excessive or fatal bounces from hotmail accounts

[Markus Neteler]

Hi,

please note that contemporarily hundreds of spam accounts are being
registered in our mediawikis. Saw this also elsewhere. The point is
that most of the confirmation emails go to hotmail and outlook.com
accounts (on the GRASS wiki Martin Landa and me get a cc email of each
of them, local hack).

I guess that they cracked hundreds of the email accounts.
