They accept, drop the message or, in the most extreme cases, can be malicious and accept and store the message and you'll never know you should had received. But, with a very small ttl on the dns record (I use 60 seconds), this risk can be reduced. Anyway, of course you should always host your e-mail on a static ip. But it is possible to do so on a dynamic one.
