I'm puzzled by this. We can see the messages go *out* without any issues, and our IP address isn't on any widely-used spam blacklist. The content can certainly trip spam filters, but in general that should just route it to the junk mailbox rather than simply not delivery it.
When we move to the new site, we'll be using a new email system, and with luck that will fix it.
In the meantime, be sure you whitelist "
daphne@mindcontroltheatre.com" and "
info@mindcontrolcomics.com", as that's where the emails come from.
