I’ve implemented the steps on this guide:
I thought this was going to allow me to use each individual domain name as the host name for incoming/outgoing, but I’m getting “The certificate for this server is invalid.” messages on my email client (Mac Mail).
Mail still works using the machine name.
Is this not the purpose of implementing this change, or does it simply remove the ‘certificate/server mismatch’ errors that some people are getting?
I’ve managed not to get those errors for a long time now (and I’m sure I wasn’t simply ignoring them) although someone using mail on their iPhone still gets multiple errors. Will this change cause those to be resolved, even using the machine name as the I/O mail server?
