I use exactly the same strategy for over a jear now, without any probs.
It's so simple.
When offline, mail is maildir-queued, while online, mail gets straight
through.
No need to fuzz with any patches to enable deferred mail dequeing.
Instead of two files (virtualdomains.online/offline), I use a script
which puts a comment before the `:alias-pppdir' line in virtualdomains, so
I do not have to change both files when I change control/virtualdomains.
The only problem I ever had, was when the ISP's smarthost is offline,
so that remote mail ends up in the normal qmail queue. In such a case, I use
a smtproutes (:[127.0.0.1]) entry, to get remote mail back to the maildir.
