I see no communication in the bug about it, and to my understanding adding _anything_ on postfix.service won't make a difference (since the only dependencies relevant for startup are on [email protected]). With ifupdown and resolvconf, and your override in place, I can still reproduce Bug#844277 (it is easier to trigger by adding pre-up /bin/sleep 5 to /etc/network/interfaces) May 10 18:26:22 voip20 postmulti[638]: fatal: parameter inet_interfaces: no local interface found for xx.xx.xx.xx May 10 18:26:23 voip20 systemd[1]: [email protected]: Control process exited, code=exited status=1 May 10 18:26:23 voip20 systemd[1]: Failed to start Postfix Mail Transport Agent (instance -).

Adding the After=postfix.service into [email protected] fixes this issue for good (because [email protected] <- postfix.service <- network.target <- networking.service) NM is a completely different beast, I think you may need to be After=network-online.target here. But static IP with NetworkManager, and having postfix bind to it, should really be seldom enough. Bernhard
