SMSMSE too many Administrator email notifications

I need a solution


we’ve got a DAG with 6 Exchange servers.

when a rule/threshold or whatever is reached the notifcation is sent multiple times with the same message to the administrator email (this is a distribution list containing 3 users).

It can occurs from the same server or from different server.

This notification was sent thrice to the same email address by the same server:

email subject : “Administrator Alert:  Symantec Mail Security detected an error (SYM:xxx442769)”

“Location of the message:  SMTP

        Sender of the message:

        Subject of the message:  mail subject

        The attachment(s) “20200-01.pdf” and/or the message was Logged Only.

        This was done due to the following Symantec Mail Security settings:

        Scan: Auto-Protect

        Rule: Encrypted File Rule

 Server Name: Server01″

Any idea ?

But the notification is received also by the destination recipient.

The rule is set like this:

Match type: literal string

Action: Delete

Message filtered when sending to messagelabs

I need a solution

Messages sent from our domain which contain our URL,, are being filtered.  If I turn off the URL in our signature line, the messages go through OK.  This happened about 2 weeks ago as well and I sent an email to and they seemed to fix it.  But now it’s back.

My Domain Emails getting blocked by Symantec cloud – need help resolving

I need a solution

Hi Team

Our Domain emails getting blocked by several other companies using Symantec cloud.

Our SPF and DKIM record are properly configured. Please help us to resolve our issue, its hampering our business. We have attached email headers for reference.

Bounce Message – 553 Message filtered. Refer to the Troubleshooting page at for more information. (#5.7.1)

Looking forward to hear from you.





SPF 5.7.1

I need a solution

Hi all,

It seems we are also being hit with the below bouncebacks for any of our tennants on Office 365 sending to anyone who uses Symantec protection.

The bounceback we are receiving is as follows (for example):

This is a delivery failure notification message indicating that
an email you addressed to email address :

could not be delivered. The problem appears to be :
-- Recipient email server rejected the message

Additional information follows :
-- SPF (Sender Policy Framework) domain authentication
fail. Refer to the Troubleshooting page at for more 
information. (#5.7.1)

This condition occurred after 1 attempt(s) to deliver over
a period of 0 hour(s).

If you sent the email to multiple recipients, you will receive one
of these messages for each one which failed delivery,  otherwise
they have been sent.

Our SPF records for all 365 tennants are up to date as they should be. Any ideas on what we can do? This is starting to impact our organisation…
