You cannot sync the queues, but you can make sure no mail gets lost. Use crosswise DRBD to write the other hosts queues to the other nodes Secondary DRBD device. In case of failure remount the DRBD as Primary on the remaining node and start a second Postfix instance that has been configured to work with this queue. p@rick -- [*] sys4 AG https://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein
