dovecot - Feb 2019 - system wakeup caused by write operations to /var/lib/dovecot/instances

Hi Timo, 

Thank you very much for replying with an instant solution!

Suggestion for future release: a setting in the configuration to
enable/disable the automatic instance_update_now action and/or set the
timeout by the user.

In the meanwhile I can use the recompiled version with this code change.
Problem solved for me. 

Regards,
Tijl

Postfix can do this without that added infrastructure.

Could you explain how this can be accomplished with Postfix?
At the moment I don't use Postfix (I use Dovecot only to store mail
archives) but I'm OK to install it, just for this.
Thank you for your advice already!
