We have a third party who is using the website www.checktls.com to verify that emails sent to our domain covermycab.com use TLS, I have setup an encryption partnership in the messagelabs portal but the website check is still failing. The primary MX record is using TLS but the secondary MX record isn't, is there anyway to correct this?

We have been using the Policy Based Encryption Advanced Encrypted Portal for a while now.
Just a quick question whicvh one of our compliance people brought up , is there any way to ensure that mail is readable only by the intended recipient?
For example if an encryped mail is sent to the wrong email address and the mistaken recipient already has an account for the encrypted portal , that person would be able to read the mail right?
The question they are asking is , is there a PBE Advanced way to ensure only the intended recipient can read the email.
This is the mail delivery agent at Symantec Email Security.cloud.

Is anyone aware of an issue adding new O365 hostnames to inbound routes on Symantec Email Security.Cloud
When I try and add O365 hostname for email delivery, I get an error message. I'm told this is a symantec issue at present (I've not seen any other status posts).
We cannot email vendors and customers using message labs. Our domain is adveng.com One vendor is ra.rockwell.com.
Remote Server at cluster6a.us.messagelabs.com (18.104.22.168) returned '400 4.4.7 Message delayed'

Thank you for your help on this matter.

I am writing as an e-mail system administrator of Alizon Industrie in France.
Since last week, it seems that our IP address is blacklisted by Symantec (negative reputation) and we need a delist as soon as possible.
To send from 188.8.131.52 to domains which are securized by Symantec our addresses use these domain names:
Today, we encounter problems with schneider-electric.com (the mails are dropped in quarantine) and michelin.com (the mails seem to be sent but do not appear in mailboxes). I've already sent a mail to firstname.lastname@example.org, but in order to solve this issue as soon as possible I create this discussion.
Could you provide us more information about this issue and about your investigations? Are there any actions you require from us?
Thank you in advance.
I have repeatedly contacted you through the IP removal tool available at https://ipremoval.sms.symantec.com/ipr/lookup.
My question is in regards to how long it takes for this request to be processed. Should I expect this to take more than a week?
I would very much appreciate an answer.
Thank you kindly.
I have done all testing I can do before posting here, I believe this to be an issue outside of my control but willing to check anything as required.
The below happens when trying telnet on any of the IPs.. EXIM gets connection timed out.
$ telnet 184.108.40.206
telnet: connect to address 220.127.116.11: Connection refused
Please advise as I need this to be resolved before I add extra clients, unfortunately I use messagelabs so its impacting me more than anything!
If it is blocked/trottled, could you advise when the last seen spammy content was?
Good Morning All,
We have an organization that is unable to email us even though we have white listed them. I can email them but they can not email us. Error message on the bounce back email they get is below. Please help.

(#5.7.1) (in reply to end of DATA command)
We found out that one of our server ip addresses is on your list.
We had an issue with one client on december (his email account was used to send spam) but this issue was fixed very soon, we have checked the entire server and found no issues, also we check all of our ips against some of the most popular blacklists checkers and we aren't listed on any (over 100 lists checked) but yours.
Please could you please delist our IP address: 22.214.171.124 we have a lot of clients complaining about emails not being delivered properly.
For the last week now we have a client who is unable to email anyone that uses Symantec Email Security. They constantly get the below message -:
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)
They use Office 365 and all DNS is correct for SPF and DKIM. They do not show as blacklisted anywhere and the majority of emails have no attachments. Strangley though if they email from the Office365 web portal the email sometimes gets through.
I submitted several emails last week and the week before to be checked for false positives but have had no response.
This is causing major disruption for the business as they are finding that more and more suppliers use theis sytem for email filtering. They have had 1 customer whitelist them which allowed email through but they do not want to have to do this with dozens of other clients.
Any help would be appreciated
