You can also do this.
At dyndns.com they offer a service called dyn email backup mx.
What this service does is catch all your email while your email server is down.
I used this service once at one office location where a email server was at because our internet service was going in and out.
Yes it was the internet service provider's fault due to some glitch in they network. They finally fixed it after a year. Drove me crazy working on it.
But here is a thought for you.
It is thinking out the box like i have always HAD to do to fix problems.
I am not suggesting you do this but with some others input it might be a work around for you.
Like you said, is there a way to pause email.
here goes
If you have a bash script that is run in the cron.hourly directory.
You should be able to start and stop the email services of sending or receiving emails at the times you choose.
You can have the email services running all night and other odd days such as weekends.
During the day, you can start,stop,suspend those services on a schedule.
When you stop/suspend the email service, the dyn email backup mx should catch your receiving emails and deliver them when you email service is back running.
Of course you have figure all this out. But for any troublesome internet connection, this might work.
I have used dyndns.com for all my services. There are cheaper services out there but i have to give them a gold star on service and support.
