Email Security.cloud

My organisation seems to also be suffering from blocked emails to/from out clients that use MessageLabs.

Our URL is 44communications.co.uk, a domain owned via LCN, run through GSuite (213.239.210.144) 

Our IT support (liaising with Google tech support) suggests the following issue:

"What is happening is the server with the IP address of 194.114.62.76 (Our Client) is rejecting our server's attempts to deliver the messages you send out to them.

I do believe this is due to the fact, that our server library is missing from their SPF record. The SPF itself is an email authentication protocol that allows the owner of a domain to specify which mail servers they use to send mail from that domain. By not having the "include:_spf.google.com" part in theirs, which contains all the IP addresses we use they might be blocking us, due to their local server settings."

Is this an issue you can resolve for us directly? As this is something that is business critical to us now, and is not isolated to just one client.

Best wishes,

Alan

Hi Alan

Could you give me a couple of example emails I could take a look at? You mention it's happening to mails both to and from Symantc clients so I'm very interested to see examples from both.

It would also be very helpful to see some examples of the error messages you are seeing. Based on the information from Google it sounds like its SPF related but if I can take a look at some examples and see the errors I can hopefully give you a definitive answer on what the issue is and how to resolve it.

Kind regards
