I'm having an issue to upload e-mail/s from my Outlook to Salesforce via the Salesforce for Outlook plugin. The issue happens only for particular account 'Streamlined Marketing Systems Inc' and sometimes the emails to this account can be successfully uploaded, other times the upload fail. Here is what I received when the mail failed to be uploaded. Delivery has failed to these recipients or groups:

The message is from email scanner (antivirus) in between your Outlook client and the Salesforce server.

Per the URL contained in your question (https://support.symantec.com/en_US/cloud/troubleshooting.64305.html), error #553 indicates the message was filtered and returned because of it having a high spam score. Evaluating those messages that fail and see what the trend is among them. They could have spam like content, a virus embedded in an attachment or even a misconfiguration issue with your mail server.

There are really so many different possible resolutions, and I would recommend starting with the easiest as previously mentioned above. Examine all of the emails that were bounced back and determine the pattern between them. If there is no pattern, then ask your company's IT to assist and check their mail servers to see if they are configured as an open relay or have been black listed online.

Good luck.
