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

  • I have recently setup mail appliance and ahce rules set.

    One of the rule is block some attachement type .

    One of the user is sending an attachement wiht .txt and the appliance is blocking it. .txt is allowed it is not in the block list at all.

    the file attachent is a certificate file (Original extention is .der) But the user is renaming the file with .txt and sending it an email attachemnt. But gets blocked/quarentined at the appliance,.

    some body have faced such issue.

    thanks
