Although I see quite a few of them from other IPs (look like commercial mailers/spammers), I'm seeing most of them in conjuction from mail from Hotmail IPs.
The curious thing is that when I send email via a hotmail webmail account, or via Live Mail (which uses the same range of IPs when sending), the emails come through perfectly. In other words I can't reproduce it.
Has anyone else noticed an increase in these in their logs? Has Hotmail done something stupid? I can't imagine they would be sending bare LFs randomly. I suppose it could be a timeout rather than a bare LF, but again, how could that be happening with hotmail?
I can't, for various unimportant reasons, install spamdyke (which fixes any bare LFs) on this particular machine, unfortunately.
