Dear Colleagues, dear Support! I'm seeing the following quite a lot recently in my maillogs. Apr 23 08:33:48 xxxxxxx postfix/postalias: fatal: open database /var/spool/postfix/plesk/virtual.db: Permission denied Apr 23 10:33:48 xxxxxxx qmail-queue-handlers: handlers_stderr: postalias: fatal: open database /var/spool/postfix/plesk/virtual.db: Permission denied I can recreate the error reliably by sending an email to two addresses: Address A (which is on the server and forwards to Address B) and to Address B directly. In this case only one email is being delivered. But I'm not sure if this is necessarily related to the issue. Is anyone experiencing similar issues and could point me towards a solution? Thanks a lot!
