Enable TLS 1.3 on efa

Post by bernikm »

Hi

We have E.F.A v4 as mail-relay before internal Exchange server, so E.F.A in receiving mail from internet.
We have an issue with some external users sending mail and getting error: Must issue a STARTTLS command first
I think we need to configure TLS on EFA ? How can this be done ?
Any help how to do this will be gladly appreciated.

Regards,
Mike

The easiest way is to enable let's encrypt and let the certificate bind to postfix ...

Do you mind to tell us how do you setup your EFA Box to your exchange server?

Is that issue of STARTTLS coming from your exchange server or your MUA (user mail client)?

Only activate it in the eFa-Config Menu

Hi

There is no option in efa-config menu to enable STARTTLS ?
We're using efa 4.0.4
