- IP is not black listed on any SBL's and DNS as well.
- Symantec IP investigation tool shows NO negative reputation of mentioned IP
- I've also sent email with de list request to: email@example.com with reply:
- "....We will investigate and if necessary setup counter measures to make sure that it is not blocked again in the future. The reason for your IP being identified as a zombie is that Symantec received what appears to be spam email traffic from your IP into its Probe Network and performed a series of tests to determine if your IP address was a mail server. Upon failing this initial test, we performed additional analysis of the email traffic prior to listing the IP."

We are facing an issue with mail delivery from firstname.lastname@example.org to email@example.com and firstname.lastname@example.org addresses.
Here's log from the server:

Messages being sent from Cloud server which is fully clean and not affected by any sorts of outgoing spam. Server's IP address is 18.104.22.168.
Could you please take a look on this and assist with resolving?
I am checking some logs from messagelabs, one of them is 'SMTP Status: blocked - timeout (#4.4.2)'. What does it mean?

We have a problem delivering mail to Messagelabs.
Our sending mail server is clean and not delivering spam, cross checked twice.
Can you please remove this IP?
We have a huge problem with our IPs and your blacklist. We have a dedicated server with a lot of mailservers IPs. We checked any strange behaviour, but we didn’t detect anything. We have IPs like 22.214.171.124, 126.96.36.199, 188.8.131.52 or 184.108.40.206 blacklisted on your lists everyday, and there are only on your lists (no Spamhaus or Barracuda listing, the only blacklist that lists our IPs is yours). Every day we have to delist our IPs with your online tool (http://ipremoval.sms.symantec.com/lookup/) but the next day, we found them in your blacklist again.
Our server is an uncompromised mailserver, with a lot of clients, each with a particular IP. All of our clients use the mail in a normal mode (not commercial sending or bulk sending). And the Symantec list is the only one that lists our IPs. In some cases, our client cannot send emails to some banks here in Spain (some of them use a MessageLabs/Symantec spam filter) and we cannot find a definitive solution.
How can we resolve this situation? Please, is extremely urgent. We can give you our server information. We checked that the emails are being sent correctly (with the MXToolBox SMTP Test Tool https://mxtoolbox.com/diagnostic.aspx). We checked all the server searching viruses. But all the the tests were good. Even so, Symantec lists us on the blacklist. Please, we need a solution. Contact me for every doubt you have.
When we try to deliver messages to some domains we receive message "501 Connection rejected by policy [7.7] 20607, please visit www.messagelabs.com/support for more details about this error message..".
Could you please help us to remove our IP 220.127.116.11 from blacklist.
Thank you in advance.
With best regards, Den
Hello. I am the administrator of the mail server windows-plesk.comel-it.com Recently, one of our clients reported that they could not send messages to messagelabs.com customers. Our server obtains the message as in the post title. The IP of our server is 18.104.22.168 and we are not listed on any blacklist. Please tell us what steps we have to make to make the small pass properly.
We have a dedicated server which is hosting several domains using cPanel. Using this server we cannot send any email to any domain that is behind the email security product.
Server is using a specific IP in OVH network as a main IP, and we own a /28 subnet too. Both main IP and the whole subnet are listed as having negative reputation due to snow shoe spamming techniques. The funny is, we don't even use the subnet but still, is listed too. We tried to use it and we can't as your product blocks a subnet and an IP that they never sent spam. For the time we own it anyway.
Our main IP is 22.214.171.124 and we own the IP block 126.96.36.199/28 , can someone of the Symantec take care of this and help me not to fall again in blacklist?
(Any maybe inform me why we are on this list anyway?)
1) Symantec is the only to blacklist our mail servers. Checked another ~40 RBLs, we are clean.
2) There's no spam coming out from our mail servers. No alerts, mail queues or whatsever.
3) There's no virus on our mail servers. Checked and re-checked.
4) Our mail servers are not open relays or sending spoofed emails.
5) Our mail servers has not dynamic IPs
6) Our inverse records are correcly registered for the name of the new server
7) Our SPF records are present and working for the main domain, DKIM too (it's a cPanel server, spf and dkim configured out of the box).
I understand that someone maybe in the same IP block (/24 ? /23 ? the whole /16 block?) maybe is sending spam and you blacklisted the whole ip block
But when a smaller IP Block is owned by someone else why you also block it?

Please someone from tech department help.
When we try to deliver messages to some domains we receive message "SMTP error from remote mail server after initial connection: host cluster8.eu.messagelabs.com [220.127.116.11]: 501 Connection rejected by policy [7.7] 3809, please visit www.messagelabs.com/support for more details about this error message"
I checked in http://ipremoval.sms.symantec.com/lookup/. And is not listed.
Could you please help us to remove our IP 18.104.22.168 from blacklist.
Thank you in advance.

My IP "126.96.36.199" keeps getting blacklisted daily & now I can't de-list it. Its currently not on any other blacklist apart from symantec. This is the bounce back email:

After months of research I came to this thread since writing does not answer anyone.
As I have been saying for months we are penalized on many VIRUS FREE, NO OPEN RELAY servers that comply with all the security rules without sending spam as your filter as it can be seen from all users who write DO NOT WORK.
Now if something does not work, the simplest thing to do is turn it off and turn it back on once.
I will send you all our IPs for which you only consider to be malicious and for which I am looking forward to being removed from the black list:
Hi, this ip are in your BL but not sending spam, please delist
i use your tools but after two days they are re-entered in the black list despite being machines...
We're experiencing problems when sending to email addresses that use messagelabs.com MX. See below;
cluster4a.us.messagelabs.com[188.8.131.52]:25: Connection timed out
I tried to connect by telnet...
This is happening for various accounts on our server which is sending from IP Address 184.108.40.206
I have used this;
to check on our IP and it tells there is no problem with the IP Address.
The IP address you submitted, 220.127.116.11, does not have a negative reputation and therefore cannot be submitted for investigation.
Can you please help us resolve this issue as it's causing me headaches!
If you have seen your mail stopped with a 553 message filtered error this means we have deemed that mail to potentially be spam and have stopped it as such.
If you believe we have stopped this incorrectly and you are a Symantec Email Security.Cloud client please follow this process in order to address this issue.
If you believe we have stopped this incorrectly but you are not a Symantec client we can still assist you. Please follow the process in this link

I need some help. We have a couple of clients who appear to be behind the messagelabs infrastructure which seems to be hosted in the UK and Germany. My network team basically blocks everything out of europe because we are a small US organization and they dont see why someone from europe would be emailing them (dont get me started!).
Anyway, I am 100% sure that emails coming to us from @erm.com and @soncellna.com are being dropped by our firewall. So I need a list of IPs or IP ranges that email could be sending emails from messagelabs. That way i can get these ips or ranges to the firewall team and they can allow traffic from them.
I only need Email ranges, or whatever would be sending out of the messagelabs infrastructure.
Thanks for the help!
i am a devops/admin and one of my clients has the problem that the reputation of the server ip is again bad (snowshoe spam).
The server is monitored and not compromised.
Is there a chance that someone here can help?
I can provide the bounce mail information by private message.
Emails to Investigation@review.symantec.com are not replied by symantec, although i see they are delivered to symantec incoming mail servers correctly from my ip.
I can remove the ip but it -maybe- will happen again and again..
