No, I did not say that, but I have seen rumors that google will drop also
the app password approach, in which case this route is not any longer
possible.
However, I don't remember where I have seen it.
Do you have information regarding this subject?

I see, I might be able that my machine will be registered in our DNS
databank as
machine-name.mat.ucm.es
I am not sure that it will help if I use my Linux SMTP server, [1].
Especially if I am using my laptop on any other institutions or at home,
since I then will have an IP address that is not within the range of the
IP addresses my university uses. I could use VPN but that slows down
things and, it also does not allow me to use newservers since that is
blocked when using non static university's IP, sigh.
If this approach (registering my machine) does not help, I have to pray
that google will stick to app passwords for the foreseeable future.
Regards
Uwe
Footnotes:
[1] (I need the from to be oub@mat.ucm.es, because otherwise my SMIME
certificate is not working)
