gmail spam help

Mainly because I own it, and the people who use it. The server has been 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 at corp.nac.net<mailto:alex at corp.nac.net><mailto:alex at corp.nac.net<mailto:alex at corp.nac.net>> to rubenstein45 at gmail.com<mailto:rubenstein45 at gmail.com><mailto:rubenstein45 at gmail.com<mailto:rubenstein45 at 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.

Is there anyone on-list that can help me with a world -> gmail email issue, where email is being considering spam by gmail erroneously?

Thanks.
