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.

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. Scott Helms Vice President of Technology ZCorum (678) 507-5000 -------------------------------- http://twitter.com/kscotthelms -------------------------------- On Thu, Feb 12, 2015 at 10:41 AM, Alex Rubenstein <a...@corp.nac.net<mailto:a...@corp.nac.net>> wrote: 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, it’s not a question of adding a filter or not using gmail; it is not me who is using gmail in this problem.
