[tor-onions] qmail as MTA to .onion emails

Hello tor-onions,

I've been trying to set up email behind an onion service with (net)qmail. Receiving works, but I'd like to send mail to .onion addresses, using qmail as my MTA if possible. `torsocks sendmail` doesn't work here because qmail's `sendmail`-like doesn't do SMTP (see [1]).

Has anyone tried this? Would hacking a `qmail-remote` wrapper to exec `torsocks qmail-remote.original` work? Would transparent proxying be a bad idea?

It isn't critical that I get this to work. I just think it would be cool.

Thanks, copyleftie
