TLS_rcpt question - enable TLS on Hub > Relay transaction

TLS_rcpt question - enable TLS on Hub > Relay transaction

TLS_rcpt question - enable TLS on Hub > Relay transaction

Hi all

I have a Sendmail question around forcing outbound TLS for messages to an external domain. Since this external domain uses a smarthost for inbound mail, I know I need to use TLS_Rcpt.

The problem is, outbound messages keep failing when Hub passes the message to Relay as that internal transaction isn't being encrypted (being on the same box and all).

Basically this is what I get:

Aug 11 11:46:47 myservername Hub[31581]: o7BGkDTj031564: ruleset=tls_rcpt, arg1=user@externaldomain.com, relay=localhost.mydomain.com., reject=503 5.7.0 encryption too weak 0 less than 128

Any ideas what I have to do? I'm thinking I need to either enable TLS on the Hub>Relay transaction, or I need to find a way to not trigger the tls_rcpt rule until the message goes to Relay.

any ideas are welcome - thanks in advance!
