Please. Gmail isn't ever likely to use long dead hobbyist block lists.

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.

around 10+ years and has tight oversight. SPF is proper. This is a recent
issue.

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 alex () corp nac net<mailto:
alex () corp nac net><mailto:alex () corp nac net<mailto:alex () corp nac net>>
to rubenstein45 () gmail com<mailto:rubenstein45 () gmail com><mailto:

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.
