Postfix version: 3.7.3

Hello all,
im trying to configure postfix for sending the mail generated by check mk.
For this purpose im using the following AWS smtp relay server: email-smtp.eu-west-1.amazonaws.com.
I’ve configured the sasl_passwd and generic file, in the main.cf ive enabled the TLS, but when i send a mail im facing these error:

I’ve looked up for the tlsmgr error but everything i found out seems to be refferred to older version of postfix.

This is the main.cf conf line related to the tls:

I’ve added the line smtp_tls_session_cache_database and the other highlightened part.

Anyone have an idea on how to remove these error or have some idea on what is the cause of this error ?

Have a look into the master.cf, if the line for tlsmgr is deactived.

Hi Robert,
thanks for the quick response.
The line was, indeed, commented. Now it works everything correctly. :grin:
