Hello,

I have an email system on IP: 93.158.211.31 and 93.158.211.34

My users and I have been getting some mails returning with: "501 Connection rejected by policy [7.7]"

The IP's mentioned above are not black listed, implement DKIM. The Symantec's ipremoval tool reports:

"The IP address you submitted, 93.158.211.31, does not have a negative reputation and therefore cannot be submitted for investigation."
"The IP address you submitted, 93.158.211.34, does not have a negative reputation and therefore cannot be submitted for investigation."

Could you please check why these addresses are getting blocked?

Thanks,

IP Removal - What will it take?

≪ Previous: IP removal

I do not need a solution (just sharing information)

I have requested removal multiple times from the Symantec IP reputation system. Never get a response, never get removed. Our clients are having their email blocked to places that are using Symantec's IP blocklist to filter incoming connections.

1. We have 2 server IP's, neither one is on any blacklist anywhere.

2. We are not an open relay.

3. We use SPF records, only have about 130 email users, and are presenting NO REASON we should be on the negative IP reputation list with Symantec.

As a last resort I have posted here. Can we get some kind of action, even if it's somebody saying "this is what we don't like about your server" so we can address the problem and keep the email flowing?

Thank you.

What is the root cause of IP in SpamCop list ?

≪ Previous: IP Blocked.

I need a solution

As posted in the ClientNet Service Alerts, there have been several cases where a Symantec IP address is in the SpamCop list.

We have had quite a few internal support cases, because email is rejected when people send email to partners that use SpamCop.

Is there a "root cause" that explains why this is occuring so often recently ?

What steps can be taken to reduce this problem ?

It is a real problem for us.

Thanks

Hi,

I am trying to fix the bad reputation my mail server has. I asked for an investigation multiple times on that web page: http://ipremoval.sms.symantec.com/lookup/ But it apparently has no effect.

So I wonder how I could clear my reputation. I am quite confident I never sent spam. My server sends very few emails. Only some user registrations for my web site.

I tried very hard to configure my server well. It is in no blacklist. DNS is well configured. My emails get the best possible score at https://www.mail-tester.com/. I have SPF, DKIM, DMARC, etc.

IP is 37.187.7.98 (www.crazy-sensei.com)

Users report that they can't receive their registration email. gmail is OK. I had to contact hotmail so that they stop blocking me. Many other ISPs seem to be blocking me, too.

I'd appreciate some help.

Thanks.

Is it possible that you could check and clear our IPs from the symantec system or maybe forward this message to a collegue that could take care of this.

We have 2 IP's blocked by the 7.7 policy.
178.32.77.130 (mail01.manact.net)
178.32.77.133 (cswd15.cswd.be)

We are a mail provider for our private customers (mail01.manact.net) and we are also hosting mail's servers in our cloud ( eg. cswd15.cswd.be)
Our customers can't send their professional emails to their clients and this situation is really critical for us.

Mutliple False Spam Positives from O365 Sender

I need a solution

I'm getting false spam positives from MessageLabs when multiple users send emails from their O365 environment to MessageLabs clients. It's not all emails, just some and has only started happening in the past 10 days. This is not happening to users of other email security software/services.

I've checked the SPF and similar configuration on the O365 side and all is fine. I've also checked blacklists and have sent emails to multiple Spam analysis sites and they've reported back that all is OK.

How do I get Symantec/MessageLabs to investigate this and provide me detail on why these emails are being falsely identified?

Thanks

Our IP has a negative reputation due to snow shoe spamming techniques

≪ Previous: 553-Message filtered

Hi:

We have a server which is hosting several domains. Using this server we cannot send any email to any domain that is behind the email security product.

According to our logs, emails are correctly delivered:

maillog:Jan 25 10:15:26 XXXXXXXX postfix/smtp[10062]: EBC616620183: to=<XXXXXX@XXXXXX>, relay=cluster8.eu.messagelabs.com[XX.XX.XX.XX]:25, delay=1.6, delays=0.9/0/0.26/0.46, dsn=2.0.0, status=sent (250 ok 1485335726 qp 29326 server-13.tower-178.messagelabs.com!1485335726!82147396!1)

However, they are never delivered to the user inbox. Some users of the Email Security have told us that they got a warning that spam was being sent and could whitelist one of our domains. Normally, what happens is that emails are not delivered, recipients get get no warning at all and we get no error message in our server's logs so the message is simply lost without anyone noticing it.

I checked the symantec IP Reputation tool and this was the result:

The IP address XX.XX.XX.XX was found to have a negative reputation. Reasons for this assessment include:

The host has been observed sending spam in a format that is similar to snow shoe spamming techniques.

We have checked several DNS black lists and the ip is not listed there. We have checked the ougoing email and we are not observing any abnormal email deliveries. Does anybody know why our reputation is negative? I tried to remove the IP using the reputation tool and it worked, but after a few hours it got a negative reputation again.

Hope anyone can help. Thanks in advance,

Alfonso

Hi there,

We run our email on office 365 and we keep getting -

550 5.0.350 Remote server returned an error -> 553 Message filtered. Refer to the Troubleshooting page at;http://www.symanteccloud.com/troubleshooting for more;information. (#5.7.1)

Out clients can't send to us and they get the same error #5.7.1

This just started happening a couple of days ago and has never happened before. This only happens with symantec/messagelabs, every other email provider is fine. SPF and DKIM are fine, no blacklists.

How can we fix this? This is a huge pain and is disrupting our business.

Thanks.

Please help. Legitimate emails are blocked by Symantec filters.

We have been assigned a new IP address(1 month ago) from our ISP and this problem arose. This IP 185.153.220.250 belongs to Metriksoft Inc, and it provides email service for pingturk.com brand. It is a Centos machine and relay access is closed.

We are getting the following logs in postfix logs:
Jan 27 15:13:33 mail postfix/smtp[49917]: 2CC8260496: XXXX refused to talk to me: 554 5.7.1 You are not allowed to connect. Please refer to http://ipremoval.sms.symantec.com/ for further information.

I made 3 requests to the above Symantec URL for removal of the IP address(It says this machine is doing snowshoe spam which is not the case).

There is no indication of progress or follow-up mechanism for the tickets at this URL. I am not sure someone is investigating or not.

Can you help us to get out of Symantec spam blacklists?
