Your iPhone should be connecting to port 587/465 and don't block
localhost.localdomain there.. clients should be able to send almost any
EHLO, just block localhost.localdomain on port 25. IMHO

I think IOS v14 changed to sending using that EHLO, it may have changed
in the latest update as far as I am aware, I haven’t followed it
extensively, but picked up on it reading various threads, I don’t think
its Malware.

Just had a client try to send emails from an iPhone using “EHLO
localhost.localdomain” which we have blocked.
I’ve never seen this before ever, so just checking if there is
something new out there.
