Email appliance unable to deliver encrypted email

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 Rahmatn,

    Regarding this case my email topology is straight forward without any encryption server except Sophos Email Appliance.

    However we must configure email server to use telco public smtp server to avoid spam  blacklist IP. Thanks
