You could investigate using a mail rerouting service (some are free). Most of these advertise the ability to reroute mail to your in-house server on an alternate port, typically when your ISP blocks port 25. What they also do is if your machine doesn't answer, they will stock up your mails for a while acting like a backup MX server. When your machine gets back online, they pipe the received mail to you. You could give that a look, if it works great... i don't personally have experience with mail caching on these services but i know they offer it.
