RE: reloading postfix with systemd

IMHO I would think they both work for backwards compatibility and over time "service postfix reload" will eventually be depreciated and no longer be a valid command. I expect that to take years. -ALF -Angelo Fazzina Operating Systems Programmer / Analyst University of Connecticut,  UITS,
