Email appliance unable to deliver encrypted email

Azwan

Hi Everyone,

Does anyone have experience or configure email appliance to use external smtp proxy to deliver email?.

I have encounter issue unable receive encrypted email from external once email appliance has encrypted and deliver to external smtp proxy, email without encrypted successfully deliver with a few seconds delay.

Appreciate if anyone can advice and suggest troubleshooting steps to troubleshoot this issue. Thanks

    Hi Azwan,

    I had a look at you the logging in your support case.  It indicates that the test messages were successfully encrypted and delivered to your upstream smtp relay. 

    You can see the message details in 'Search > Mail Logs' on the SEA.  There should be a 'Delivered' section which will show the IP the message was delivered to (Your upstream smtp relay).  This will also show you the response from the relay, usually with a message ID.

    I'd recommend to check the logging on your upstream relay to see what happened to the message.  Also, are there any settings on the relay that might remove an SPX message?  For example, rules that block specific attachment types (PDF) or unscannable attachments will interfere with SPX messages.

    Sorry we couldn't be of more help but you may need to contact the vendor for your upstream mail filter/proxy.

    Thanks,
    Tom.
