Now which clarifies things a lot. I'll probably keep 465 with wrapper mode to
support outlook expresss or other clients which want it and put 587 without.

MS Outlook Express was depreciated in Windows 7, way back on Oct 2009. It has
been years since I have seen anyone actually use it. I removed wrapper mode 5
years ago and never looked back.
I've seen comments from users/admins who recommend using SSL-only ports like
465, as opposed to 587 where plaintext is technically possible.
I've also seen problem where port 587 was blocked by antivirus trying to
scan the connection, where 465 went OK.
That's why I better provide both 587 and 465 on servers I maintain...
