I have 2 domain registered on Virtualmin. After yesterday update of webmin, posfix not deliver mails. If I send mail between two virtualmin domain, postfix not resolve host with Virtualmin hostname . Postfix not expand corectly address. But DNS chceck of all address is OK. Can be problem with procmail-wrapper? Or?.

Problem solved. After system upgrade non-FQDN hostname was removed from mydestination in main.cf . But I don’t know what remove it. Debian instaler, upgraded package post-install script or etckeeper. I’m going to continue my investigation. THX

I would guess it has nothing to do with the Postfix mydestination configuration. I’m guessing the system hostname changed.
