Unset Postfix smtpd_tls_session_cache_database, reduce disk writes ( #3981 )
...
Postfix may update smtpd_tls_session_cache_database quite frequently even on not busy server, which leads to unnecessary (excessive) disk writes, which is an issue for SSD.
Postfix documentation suggests not to use this parameter anymore since there's another, better TLS session resumption method available.
>As of Postfix 2.11 the preferred mechanism for session resumption is RFC 5077 TLS session tickets, which don't require server-side storage. Consequently, for Postfix ≥ 2.11 this parameter should generally be left empty.

Added the delay_warning_time (http://www.postfix.org/postconf.5.html#delay_warning_time ) with 4 hours as setting. Postfix will inform the user that the e-mail has not been delivered, but that it will try for the next 5 days.
There is also a setting called confirm_delay_cleared (http://www.postfix.org/postconf.5.html#confirm_delay_cleared ), but according to the Postfix this can lead to a sudden burst of notifications at the end of a prolonged network outage.

Update main.cf

I was looking into creating a backup mx server for a high availability mailcow setup. It seems that this is not easily done. While researching to find out how long an average SMTP server keeps trying to send to a server that is down I found that RFC 5321 advises at least 4 to 5 days. Mailcow has a custom setup of 1 day, which is very short. The user will be unaware for 5 days that his mail has not been delivered, which can be negative. But I still would like to follow the advice of the RFC.
RFC 5321, in section 4.5.4.1, has this to say:
Retries continue until the message is transmitted or the sender up; the give-up time generally needs to be at least 4-5 days. It MAY be appropriate to set a shorter maximum number of retries for non-delivery notifications and equivalent error messages than for standard messages.
Postfix default is also 5 days: http://www.postfix.org/postconf.5.html
