We had to manually remove it from spamassassin for our local installation, and I am pretty sure that a lot of sites still haven't figured it out so there's a lot of false positives being generated all over the place to throw off even filters that don't use it directly.

I'd be interested to know how you can be so adamant about the lack of spam from 
this specific server.  A great percentage of the spam hitting servers I have 
visibility into comes from very similar kinds of set ups because they tend to 
have little or no over sight in place.

Also, lots of commercial email gets flagged as spam by users, even when they 
opted in for the email.  If enough people flagged email from this server as 
spam it will cause Google to consider other email from the same small server as 
likely to be spam as well.  Small systems, especially new ones, tend to 
unintentionally look like spam sources by not having proper reverse records, 
making sure you have SPF set up for the domain, etc.

I should have been clearer.

I have been getting complaints from my sales folks that when they send emails to people who use gmail (either a 
gmail account or google apps) that they recipient is reporting that the email is ending up in the Spam folder. So, 
I tested this myself, sending an email from 
a...@corp.nac.net<mailto:a...@corp.nac.net><mailto:a...@corp.nac.net<mailto:a...@corp.nac.net>> 
to 
rubenstei...@gmail.com<mailto:rubenstei...@gmail.com><mailto:rubenstei...@gmail.com<mailto:rubenstei...@gmail.com>>

This is curious to me, since @corp.nac.net<http://corp.nac.net> is a small 
exchange implementation with only about 50 users behind it, and there is no question 
that there is no spamming going on from here.

So, it’s not a question of adding a filter or not using gmail; it is not me who 
is using gmail in this problem.
