spamassassin with gmail

[Michael Grant via users]

Do any of you use spamassassin with a gmail account, and if so, how are 
people doing it?  The reason to do this is gmail's spam filtering isn't 
perfect and you don't have the control you have with spamassassin.

We built some plumbing to do this using gmail's API, and also IMAP which 
can work with other services such as yahoo or outlook.  I'm wondering if 
this is of any use to anyone other than myself.

Essentially, it's a daemon that connects to the account and acts as a 
mail client (an MUA).  When messages arrive in a mailbox (could be any 
folder really), sucks out the message, runs it through spamassassin, and 
puts the result either into the Spam folder or Inbox.

I'm just wondering what to do with this plumbing software, if it should 
be open sourced or run as a service.  Running it as a service couldn't 
be free as I don't have access to free servers.  The daemon in it's 
current state is a bit complicated to set up on it's own but it could 
definitely be cleaned up, especially if there was sufficient interest.

I bet this could also be put together using getmail5 instead of this 
special built daemon but that would imply polling instead of push.  
Several ways to do this.
