A few years ago, I was involved in a rather noisy and long debate here.

Since then my mailbox has been targeted by an inundation of what appears to be retaliatory/sabotage messages.

As a result, I decided to stay away from the SolidWorks forums. It is a shame, because I admire the company and its products.

The messages in question have a stealth nature and are not easy to block. I found a solution which lasted for a couple years, but the deluge came back with a vengeance.

It took me a lot of time to investigate the issue deeply. See two solutions below.

Due to the fact that all the messages contain a from header @solidworks.com and links to this website, which damage the company's reputation, I would expect SolidWorks corporation to do something about it.

============================

(1) How to block the offending messages using sendmail:

Add the top line (envelop sender) to the access.db file. In my case:

bounces+10c-ramon=company.com@provider.net       ERROR:550 " We don't accept mail from SolidWorks spammers"

(2) How to block the offending messages using spamassassin

Add the following entry to the file user_prefs:

blacklist_from *@solidworks.com
