Hey rfg, Just curious…any reason to not use use the could-based Postfix server + something like Dovecot and then have your clients access that directly? I have this now for at least 20 domains and it works awesome.
I’m not understanding why the need to relay the mail to your local Postifix instance…I’m sure there is a good reason but I’m just not seeing as yet… > On Jun 9, 2019, at 1:42 PM, Ronald F.
