Message rejected as spam by content filtering

Mx.google.com rejected your message to the following email

We’d like to introduce a “consecutive bounce threshold” instead of a “one and done” scheme, where an email address must bounce X times in a row before being flagged as “Do Not Email.” This limit can only be applied to such forms of bounces (block bounce, unknown bounce). For example, we don’t mind if the “Hard bounce – Inactive Account” message is suppressed right away because it’s an invalid email.
We’d like to adjust the logic on how Pardot treats hard bounces because there are a number of bounce forms that don’t necessitate the email being marked as “Do Not Email.” These “block bounces” can be resolved by either modifying the content piece or asking the receiver to whitelist you.

Mdaemon spam filter and email security best practices

Hello there, Since I’m not very familiar with Trading, this mistake has thrown me for a loop. I got a call from a customer who said they couldn’t send emails to one of my colleagues because they were getting the “The following recipient(s) cannot be reached” mistake. This can also happen while attempting to send emails to other people. I looked for a solution by searching for ‘#5.7.1 SMTP;550 5.7.1 Message rejected as spam by Content Filtering’ but couldn’t find one. Any and all ideas are accepted and deeply appreciated. Thank you.
The first place to look will be at the device that is delivering the message showing that it is spam. If the problem is caused by the remote system, you can try to figure out why. Is it because of content filtering, or are you on a blacklist? You can verify whether your mailserver is blacklisted on mxtoolbox and many other websites.
The sender is the first place I’d check to see why your email system is rejecting inbound messages. If you’re receiving email from places other than them, it’s probably a problem on their end. It’s possible that they’re sending mail to the wrong address or that their routing is incorrect.

Email bounce backs and error codes can be perplexing and deceptive. To assist with this, we’ve started a new blog series devoted to unraveling these mysteries. Go here to read all of the blogs in this collection.
While the IMF can be useful, it can also be a hindrance if you, as the server administrator, don’t recall or even know it was installed in the first place.
When you have a third-party filtering service in place, this can be particularly problematic.
If you have IMF installed, it means your mail is being filtered twice: once by a third-party spam filter and again by the Exchange Server. When 3rd Party Filtering is used, we usually suggest turning off the IMF functionality. Of course, this is just a suggestion, and you can do whatever you think is best for your network.
When a message enters an Exchange Server with IMF enabled, IMF evaluates the message’s textual content and assigns a Spam Confidence Level (SCL) rating from 1 to 9 based on the likelihood that the message is Unsolicited Commercial Email (UCE).
This rating is then compared to the threshold set in the Exchange System Manager’s Message Delivery Properties > Intelligent Message Filter.
