The problem here is that Mark is using a shared hostmonster smtp server 
to relay outbound mail, and from time to time they relay spam and get 
blacklisted for it. We've experienced a similar thing from time to time 
where we have a server hosted with hostmonster that sends out 
notification emails which are relayed via shared hostmonster mail 
servers, and occasionally we get bounce notifications where 
hostmonster's outbound relays are blacklisted (I have mostly noticed 
them being blacklisted by SpamCop).

If it's important I'd suggest not using shared resources for your 
outbound mail. If you use a dedicated server (with it's own IP) for 
outbound mail you will know it's clean and hopefully not get 
blacklisted. You get what you pay for.

Simple fact in the second decade of the 21st century is "their server, 
their rules". If someone wants to block you they can and they will. If 
your outbound server is spamming me I'd block you too. I don't care how 
many other people might be using it. It's not difficult to prevent 
outgoing spam, be responsible or be blocked. My server, my rules.

As you've found out, twice now, it's highly effective and gets people's 
attention. As it's got your attention twice now, I'd suggest you either 
get used to it or move your outbound mail to a clean host. It's been 
going on long enough now that it's pretty obvious hostmonster don't care 
(if it's on my radar, it must have caught their attention - after all, 
it's their servers). They are happy to keep taking your money.
