I currently use my ISP's email gateway as a smarthost so exim4 is
configured this way which is how you are able to read this
message.
I authenticate using a secret password and ssl which all
works right now but I found out I can also use the mailhost from
the employer I retired from which might have some advantages as
far as stability goes.
They sent me a link for how to install thunderbird which
I don't want, on a Linux system, but they told me that one must
set thunderbird to use oauth2 for authentication which makes my
question boils down to: Can exim4 do this?
At least we are down to the name of some authentication
process which gets the mta talking to the smarthost.
Thanks for any good ideas.
