[Giorgos Kontopoulos]

I finally did the update to latest obsidian but ever since I have a problem with postfix

but the gist of the problem I believe is here

ERROR while trying to create directory


Check the error reason (see log file: /var/log/plesk/install/plesk_18.0.27_installation.log), fix and try again

I am settling with Qmail for now
<code>/usr/local/psa/admin/sbin/autoinstaller --select-release-current --install-component qmail</code>
as this does not give me any error but I would like to resolve this problem as QMAIL does not support sending from the domain's assigned IP

Any help would be appreciated
