Our email system was compromised yesterday, meaning we were used to send a lot of spam. I've stopped the spam now, and as Get Desperate! seems to have been the source we've shut it down temporarily. I am manually letting outgoing email out in batches, so you may find post notifications come in gluts for the forsseeable future. Some ISPs, such as Yahoo!, have temporarily blocked us and you will not receive any emails if you are with them until they have cleared us.
