Urgent request please
Symantec I hope you are monitoring your forums
Any business emails we are sending to any of our clients using your message labs email filtering service are being bounced with a '553-Message filtered' error message. This only started yesterday. I have ran all the checks suggested on your website and I believe there is no issue with our email service. I have submitted some False Positive submissions but no one has got back to me. Please can someone investigate this urgently for me as it is causing us great issues with our clients. Please can someone get back to me as soon as possible
My company is having a huge problem sending to recipients using Symantec.cloud email filtering.
Our company uses the email domain @good.do to dispatch emails.
The server response is:
"553 Message filtered. Refer to the Troubleshooting page at http://www.symanteccloud.com/troubleshooting for more information. (#5.7.1)"
Can you please help?
Symantec is blocking our emails and return the following the bounce back message
" -you are trying to use me [server-12.tower-400.messagelab\r\n553-s.com] as a relay, but I have not been configured to\r\n553-let you [xxxx] do\r\n553-this. Please visit www.symanteccloud.com/troubleshooting\r\n553- for"
what could be the reason for causing this issue?
Is our IP blacklisted in Symantec blacklisting system,
Could you please prove more information on this issue, why it is causing and what steps the client should take to make sure this should not happen again
Awaiting an early response from your side
Help me, when send email to my customer ( ccamatil.com ) i getting Mail Delivery System message. 553-Message filtered.

553 information. (#5.7.1)
One of my staff is unable to send email to the particular email address.

Refer to the Troubleshooting page at 553-http://www.symanteccloud.com/troubleshooting for more 553 information. (#5.7.1)> #SMTP#”.
IT hasn’t been an issue last two years just happen from last week.
Can someone help me with tha one?
Please whitelist our IP address in your firewalls, 126.96.36.199 , it does not seem to be listed as poor reputacy.
Our clients can't send mail due the following connection problems in Exim log:
2018-07-06 22:02:37 1fbQx0-0006Ho-Qc H=cluster5.eu.messagelabs.com [188.8.131.52] Connection timed out
telnet on 25 doesn't work, but from other servers in the same subnet it works.
telnet cluster5.eu.messagelabs.com 25
telnet: connect to address 184.108.40.206: Connection timed out
telnet: connect to address 220.127.116.11: Connection timed out
telnet: connect to address 18.104.22.168: Connection timed out
telnet: connect to address 22.214.171.124: Connection timed out
telnet: connect to address 126.96.36.199: Connection timed out
It worked until around noon today (EET)
Please help, we are losing money.
At the beginning of June 2018, we acquired a new dedicated server.
We soon learned that its IP address had a bad reputation before we acquired it.
About four weeks ago, I submitted our IP address at http://ipremoval.sms.symantec.com/lookup/
It was soon after that I was finally able to send e-mail to fedex.com addresses.
Recently, I learned that e-mails are not able to be sent to domains that use clusterX.us.messagelabs.com mail servers.
Connection attempts are timing out.
Currently, http://ipremoval.sms.symantec.com/lookup/ shows "The IP address you submitted, 188.8.131.52, does not have a negative reputation and therefore cannot be submitted for investigation."
However, it seems that our IP is being throttled or blocked.
Please clear this up.
We have issue with Symantec Cloud cluster5_us_messagelabs_com.
Symantec Cloud cluster5_us_messagelabs_com stop receive messages from as to 6 domain.
We have notification.
421 Service Temporarily Unavailable
We don't have any issue with other domain.
So, I was send email to 'email@example.com' with description and I'm not receive feedback or any other reaction.
as similar stated in several other posts I have an issue with sending emails to messagecloud users from our dedicated server. We are using the swift mailer built in in TYPO3 for sending system mail notifications to our customers. One of our customers delivered us a mail of this kind:
Delivery has failed to these recipients or groups: XXXX@XXX.XXX A problem occurred while delivering this message to this email address. Try sending this message again. If the problem continues, please contact your helpdesk. The following organization rejected your message: cluster8.eu.messagelabs.com.
I don't know if it has something to do with our IP address, but I would like you to check, therefore we can either do something about it or search for another solution. Our ip address is 184.108.40.206
Thanks in advance and let me know if I can do something at our end.

How fix this problem?
We cannot send emails to messagelabs customers, our exchange queue shows a 421 4.4.2 Connection dropped due to ConnectionReset error. I confirmed our sending IP 22.214.171.124 does not have a negative reputation and I can telnet to cluster1.us.messagelabs.com and cluster4.us.messagelabs.com from the exchange server.
How can this be cleared up? Our client cannot communicate with their bank and one of their main customers....
I am very happy to use Email Security Cloud because it's very easy and giving me full-time security protection from spam and thread email. My company Custom Packaging Boxes UK and Custom Boxes (Brillant Packaging Suppliers) will use their products again.
I am not able to send to messagelabs.com from my work domain. I am not black listed but we do send a lot of emails to customers using messagelabs.com.
HI, I'm helping someone evaluate mail filtering systems and my background is with the Barracuda Email Security Gateway. It does just about everything the customer wants except it is not in the cloud(!). So we are looking at other solutions.
Can someone give me some guidance on the Symantect offerings? Is there a good document to help me find the answers?
Thanks for any advice!
I see from the forums a few people having similar issues so I'll cut to the chase;
Our details (sender);
126.96.36.199 > server1.ssab.ws
188.8.131.52 > mail.ssab.ws
Our Bank details (receiver);
anz.com MX preference = 10, mail exchanger = cluster3vk.eu.messagelabs.com
anz.com MX preference = 20, mail exchanger = cluster3vka.eu.messagelabs.com
Our hosting services have confirmed that the emails snet has been received by the bank's email server.
We can receive bank emails fine.
Please whitelist us or whatever needs to be done so we can resolve this issue, crtitical that we have email comms with the bank!
I hope that is enough info, please email firstname.lastname@example.org if you need more details
Thanks in advance and hope to have resolved within 8 hours :)
We receive approx. 15 k e-mails per day on our mailserver (Ubuntu 16.04, Postfix).with mandatory TLS encryption (smtpd_tls_security_level = encrypt). Mandatory TLS works great against spam.
mail1.bemta2?.messagelabs.com connects to our MX mailgw.gkd-el.de. Most times the mails can be transferred (142 last week). But a few times the messagelabs.com-server connects and after 5 seconds it disconnects without sending everything (5 times last week).

Other mailservers with STARTTLS can send 100 % of their mails; without STARTTLS they disconnect in 0 - 1 seconds and can't send anything. Only the servers from messagelabs.com disconnect after 5 seconds.
As a workaround we blocked the messagelabs.com IP-ranges (https://support.symantec.com/en_US/article.INFO453...) on our primary MX mailgw.gkd-el.de and installed a secondary MX filter.gkd-el.de, only visible for the messagelabs.com IP-ranges and some ohter (ssl-tools.com, checktls.com, ...).
Why do not use the messagelabs.com-mailservers STARTTLS sometimes? A problem at messagelabs.com?
We're getting 553 filter errors from Symantec when sending email to the following domains:
Problem started about a week ago. I've checked, we don't seem to be on any blacklist or anything like that. I've put in a ticket to CLOUDfeedback@feedback-87.brightmail.com 4 days ago with subject : False Positive Submission. I attached the headers of only one of the affected emails. Would love some assistance in getting this resolved...it's been a bit of a headache. Is there anything I can do to expedite? Thanks guys!
Here is the filter message:
** Message not delivered ** There was a problem delivering your message to email@example.com. See the technical details below, or try resending in a few minutes. Learn more here: http://www.symanteccloud.com/troubleshooting (Warning: This link will take you to a third-party site) The response was: 553 Message filtered. Refer to the Troubleshooting page at http://www.symanteccloud.com/troubleshooting for more information. (#5.7.1)
We recently experienced what several other forum members have experienced with our emails getting blocked due to being flagged by Symantec's solution(s).
I am looking for any advice on getting information from Symantec to help us with understanding and/or troubleshooting our issue. We are not a marketing firm and the messages that were blocked were not marketing related. Simple one to ten people exchanges of information with minimal attachments.
We were told we were added to the list due to SPAM related activities, specifically adult oriented SPAM. Upon review of our environment we are having a hard time pinpointing a source and would like data on originating IPs, domain info, or date/time stamps to help us. Essentially, mail header information would be good. We have requested the information from Symantec during the email exchanges but have received no information back.
This has happened twice in the last 3 weeks and has taken several days to review. We think we have solved the problem.
Does Symantec have a location where we could see this information and/or request the information to assist us? We want to do the right thing but if Symantec is unwilling to share the data, it makes it very hard.
Anyone have any suggestions? Any Symantec reps on the board that could help?
Thank you all for your help.
Looking for support from a Message Labs/Symantec employee. Last week I was confused as to why emails from my office to my wife's Gmail were not coming through. Since last week, on July 19th, the messages have come in sporadically. This morning, July 24th, another email came through, 5 days delayed. Looking for an explanation for the delay, and hoping the answer will help others who are asking why their emails aren't being received.
I've attached the internet headers as well as a screenshot indicating the 5 day delay, and also that the mail server in question is on a blacklist, which might explain the issue.
I've removed some identifying information such as the email addresses and subject information of the email. If a Symantec employee wants the intact header please contact me privately.
We are facing a trouble to send messages, the IP 126.96.36.199 (from Symantec MessageLabs) is blacklisted.
And we're not able to send e-mails when the outbound traffic goes from this IP.
Could you please help me?
