The recent change [1] to the systemd service results in postfix failing to start [2]. Commenting out the `RestrictAddressFamilies` option resolves the issue for me. Is there a USE flag or kernel option required for this? [1]: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=6d1bfd687106fcb4a75e0d225d77153f2b9c581d [2]: https://pastebin.osuosl.org/45171/raw/
Adding systemd to cc
There shouldn't be any requirements for this to work. Let's try to figure out how to reproduce this issue... 1. In your kernel config, do you have CONFIG_IPV6=Y, or if it's M, do you have the module loaded? 2. In /etc/postfix/main.cf, what's the value of inet_protocols? 3. Instead of removing the line, does it work if you change it to RestrictAddressFamilies=AF_INET AF_NETLINK AF_UNIX ?
Please also provide emerge --info, along with the version of systemd being used.
Sorry for the delay! > 1. In your kernel config, do you have CONFIG_IPV6=Y, or if it's M, do you have the module loaded? CONFIG_IPV6=y > 2.

It still complains about both IPv6 and IPv4 not being supported protocols.

This seems to be a known bug: RestrictAddressFamilies= broken on 32-bit #4575 https://github.com/systemd/systemd/issues/4575 I can confirm, that commenting out RestrictAddressFamilies makes postfix start again.
This issue was fixed in systemd 233. Current stable is 236.
