Macos server 5.47/3/2023 ![]() This has been an agreed convention for many years and not easy to change by anyone. Port 25 is used by every mail server in the world to send/receive mail. Is there a way to force port 587 as SMTP in the "add server account", forced from the server side? ![]() That can be easily fixed by adding a manual IMAP account to force the iOS clients to use 587 but why does a auto server account setup differ between iOS and the Macs? I verified with tcpdump on my router and that confirmed the iOS clients were trying 25 but the Macs using 587. The weird part is that my MacBooks and iMac can still send emails suggesting they're using 587. After a thurough investigation it turned out my ISP decided to block port 25 (long overdue I presume but I wasn't even aware the clients were setup using port 25 in the first place, thanks to the magic "add server account"). It's been working well until today when I was no longer able to send email with my IOS devices but the Mac computers worked fine. The downside is you can't see any of the underlaying configs in the client settings (ports, auth, ssl etc). Right away contacts, email, calendar etc worked out of the box, very smooth way of configuring I must say. All clients (both iOS as well as Macs) have used the same procedure, i.e Settings->internet account->add->another->Server account where you put server address, username and password, that's it. ![]() I have a macOS server up and running (macOS Sierra with Server 5.2, initial install was Yosemite, upgraded to elCap and now Sierra) at a remote location and a dussin clients connecting to it. ![]()
