ESA + CRES on TLS failed connections

daro

Hi,

is it possible to have either content/message filter or some other solution to have a failover on TLS failed connections for a CRES envelope?

 

best case scenario would to have CRES configured to be used when a TLS connection fails.

 

any ideas?

thanks
daniel

Hey Daniel,

 

On the ESA (outgoing rules only) you can  configure emails to be sent with encryption profile configured and to use TLS and only fail-over to CRES when TLS fails.

 

However as shared, it's restricted to outbound traffic only - requires the encryption profile and CRES account and trusted TLS domains (cannot be applied globally, only via the list on CRES portal under your account).

 

Regards,

Mathew
