Puzzled by spike in bouncebacks |

I sent out the latest edition of my ezine this morning, and was surprised to see a lot of "message failed" notices in my inbox. Normally I receive a handful of these with every issue -- about 1% of all messages sent. But this time it was a lot more, closer to 4 or 5% of all messages sent.
I have had a lot of new subscribers this past week so I thought maybe that had something to do with it. But amongst the "failed" notices are people who have previously received my newsletter with no problem.
I ran my IP address through a blacklist check this morning and it came through pretty clean. Only one red flag, and that's been there for a while. In other words, if that was the problem, it would have been causing bouncebacks before this.
(BTW, if you want to check to see if your mail server is on one or more blacklists, go to http://www.dnsstuff.com/ and enter the IP address in the first box of the middle column -- the one labeled Spam Database Check.)
I also run every issue through a free service that scans for words that might trigger spam filters (http://www.ezinecheck.com/check.html). As always, I fixed any flagged words before broadcasting, so I don't think THAT's the problem either.
At this point, I'm fresh out of ideas. Can anyone speculate at to what might have caused this spike in delivery problems?
