zhb·3 anni fa·discussiRedMail author here (Zhang Huangbin).It's quite reasonable that vendors don't support BSD due to the input-output ratio.Maybe there're many BSD servers, but not many BSD EMAIL servers compared to Linux.Take some real numbers of some iRedMail release, when it's been deployed on 22832 linux servers[1], only 300 BSD servers[2] deployed.[1] Including Ubuntu 20.04 + 22.04, Debian 10 + 11, RHEL/CentOS/Rocky/Alma 8 + 9.[2] Including FreeBSD + OpenBSD.
