Who'd be a spammer?

Tonight I've been mainly typing addresses into my Outlook Express address book.
I got over 50 addresses from the Einstein@Home team website -as team founder I can see such stuff- and with way too much fiddly cutting & pasting made a group. I then composed an inspirational e-mail and pressed the send button.
Bums! My server rejected the message on the grounds of "too many recipients". It doesn't like any more than 12 (c'mon, I'd have to be a really ambitionless spammer to want to spam just 13 people). However after lots more cutting and pasting I made 5 groups and finally sent my message 5 times. You may have got it. Hopefully lots of lapsed members will have also and will flock back to us like lost sheep redeemed.
So now, before bed, I will update the website at last.
