    Hi:

    We're a small ESP and it seems that the following IPs are blocked by message labs. They do not appear here, but there's no bounce message b/c the connection is failing.

    Per Richard Brittain here https://www.symantec.com/connect/forums/ip-blacklist-removal starting a separate thread.

    Affected IPs are:

    74.208.221.191 
    74.208.8.75 
    74.208.14.106 
    74.208.8.174 
    74.208.13.17 
    74.208.147.114 
    216.250.117.210
    74.208.144.46
    74.208.68.249
    74.208.68.144
    74.208.68.181
    74.208.65.157
    74.208.47.126
    74.208.47.60
    74.208.144.49 

    Happy to discuss offline at my forum address if we have to. All these IPs have sender scores of 97 or better; this makes no sense to me.

    Hi All,

    We have run into an issue regarding bouncebacks when sending emails to clients. 

    This has never been an issue before, but it is increasing day by day.

    Our sales team sends out offers for their products. However, recently more and more bouncebacks are happening. We have searched through our exchange logs and have found no such correlation of why this issue keeps occuring. 

    fig.1 example of bounceback message

    Any ideas of why this keeps happening more and more frequently now would be much appreciated.

    Hi

    Our users are getting boune backs from addresses using message labs to say Messages are filtered.

    Our IP was listed but has been removed but we are still getting bouncebacks.

    Can you whitelist our IP 89.100.15.226

    Hi,

    We've configured postfix in Ubuntu 16.04  that will relay mails to our mailserver. It is realying all mails through our mailserver. Mails belongs to other domains are not sending( Got bounced ) but ableto send mails belongs to our domain ( mcci.com ).

    We've checked the logs of mail, it is clearly showing that the IP which is assigned in DreamCompute VM got blocked by symantec.

    please have a look at the error message below:

    Hello,

    We receive emails from ts.fujitsu.com to momalogitech.com. in our Linux server cp426.webempresa.eu

    When the emails come from 195.245.231.0/23 arrive in few minutes but when they come from 195.245.231 they always have important delays, about 8 hours...

    We tried to sniff the traffic before the firewall and we didn't detect any connection to our pot 25 from that network before the emails arrive.

    Could you bring some light to this issue?

    Hello,

    I am writting as Linakis Digital company's System Administrator.

    We have a mail server which cannot send mails to some domains (vodafone.com / minerva.com.gr) which use as SMTP cluster5.eu.messagelabs.com & cluster3.eu.messagelabs.com.

    Below is telnet outcome from this server.

    C:\>telnet cluster5.eu.messagelabs.com 25
    Connecting To cluster5.eu.messagelabs.com...Could not open connection to the host, on port 25: Connect failed

    C:\>telnet cluster3.eu.messagelabs.com 25
    Connecting To cluster3.eu.messagelabs.com...Could not open connection to the host, on port 25: Connect failed

    Note that from our other Mail server we can send emails and we can telnet on port 25.

    We also tried blacklist tool http://ipremoval.sms.symantec.com/lookup/  and we got response " The IP address you submitted, X.X.X.X, does not have a negative reputation and therefore cannot be submitted for investigation."

    Please advice and also inform us if there is a way to send you the Mail Server IP on some private message to further investigate.

    I'm the admin of an Exchange 2010 server at my company. All emails that we are trying to send to a company that uses your messagelabs services are being delayed by as much as two days. We have no such issues with anyone else. Our Exchange 2010 server is sending these emails from 173.162.26.233 . Your client that uses messagelabs servers is at the domain capitolconstruct.com. Please fix this as it is business critical that we are able to communicate with this company in a timely manner and without any delays. Your client has already tried to contact your tech support, but after several frustrating days and exchanges of our SMTP logs with your tech support we are still experiencing the same issue due to no fault of our own.

    Thank you!

  • 03/29/18--07:26: Email bounce back
  • I need a solution

    Hi

    I am having problems email 2 seperate companies that both use symnatec cloud.

    I have checked the blacklists and that is fine and checked with my ISP twice and they confirm that everything is setup fine. It started happening 2 days ago. What is more strange is that I tried 2 different email addresses and both bounced back. Do you have any idea what to do. I have just tried sending one an email through webmail to see if that works.

    Thanks for any help.

    Hello,

    Recently emails from my corporate email server to companies using your service started failing. In looking at the SMTP logs, i see our servers set up the connection, you send me your certificate, i send mine, then i start sending the message. I'm posting a portion of the logs after the cert exchange:

    Hello,

    a new public IP network class has been recently (Mar 2018) assigned to our company but now we are experiencing problems due to messagelabs.com filtering policy.

    Our network is: 62.173.161.0/28
    16 ips from 62.173.161.0 to 62.173.161.15

    The error trace:

    host cluster5.eu.messagelabs.com[85.158.136.83] refused to talk to me: 501 Connection rejected by policy [7.7] 3604, please visit www.messagelabs.com/support for more details about this error message.

    I know that those IP could have been used in the past (not from us) for sending spam, but now they are clean.
    Could you remove us from you black list or make a new evaluation to this IP group?

    Please soon. Our customers start complaining about the undeliverability of their messages.

    Thanks for your time and help, please let me know if you need something else.

    I need a solution

    I am having the same problem as in this thread: https://www.symantec.com/connect/forums/messages-not-arriving-users 

    There are no instructions in that thread on what to do if the problem occurs, except send some sample to a random email address that isn't even part of symantec (brightmail??) ... I am not understanding how you don't have a proper process for resolution of email problems? Especially when you do not give clients any indication that messages are failing to be delivered.

    Please advise.

  • 04/09/18--14:33: Quarantined by message labs
  • I need a solution

    We have some external clients that are protected by message labs and all the sudden they started getting our emails quarantined.

    We would like to know why these messages are being quarantined so we can be sure to resolve these issues.  We did find that our IP was black listed by SORBS but has been delisted.

    Would like to confirm that is why we were being quarantined.
