email

I have a Dovecot mailserver running at home on a flaky cable connection. For the most part, the IMAP functionality works beautifully, but I'd like to add one feature if I can: I want Dovecot not to serve large messages to high-latency clients. That is to say, if someone decides that it's a good idea to send me a 9.3mb email to me, I don't want to get it unless I'm on my LAN at home.

This can't be an uncommon request, but I'm having trouble finding the configuration option in their documentation. Any ideas and/or good keywords to use in Googling would be awesome.
