Why do you think this isn't secure?

Gmail wouldn't let me run my own spam and AV solution. My external server 
gives me full control, with sendmail, MIMEDefang, SpamAssassin, ClamAV, 
dovecot, and procmail. I could, in principle, keep a remote copy of all my 
mail there and dsync it to my home server. I'm using fetchmail (with SSL 
option) only because I didn't understand dsync when I set it up.

I'm still a bit unclear on how dsync decides which users to sync. All my 
users are real system users, not virtual users. I'd like to retire my 3 
older accounts on my home system to never receive email again, only provide 
it for archival reading, and direct all my mail to new accounts that could 
be dsync'd to the leased external server. So I'd want to limit dsync to 
only sync the new accounts. Which might even be virtual.
