smtp_helo_name = mail.aus-city.com assuming, 203.206.129.129 is the "outgoing" IP. if you have multiple "outgoing" IPs, just live with that. most people won't check this (unless you server has a "bad" reputation that causes additionnal/aggressive checks). > There are 28 domains on the server all on individual IPs. > when it comes to email, all domains can be served with one IP. so if 203.206.129.129 is the "outgoing" IP, use it for all these domains (for smtp I mean). the alternative is to run one postfix instance per IP/domain, but that's a lot of work (and may be tricky). > Any solution or live with it?
