A brief update:

I was traveling when I first noticed this bug, and I have been
traveling since then. So I do not quite know what kind of internet
connection I have been using and certainly this is an aspect I
cannot investigate.

But I can say that somehow the error messages I get have changed:

make-network-process does not hang anymore, that's good. But I still
cannot send emails. I am surprised that Emacs never asks me for a
username / password for the remote server. Indeed, it seems that
emacs assumes that it can establish a connection to the smtp server
without this. But when emacs passes the "RCPT TO:..." to the smtp
server, the server says

554 <winkler@gnu.org>: Recipient address rejected: Access denied

(no matter what valid email address I use as recipient)

I do not know how the new code is supposed to work here. Emacs 23
had the variables smtpmail-auth-credentials and
smtpmail-starttls-credentials. But these do not exist anymore.
How are these things supposed to work with the new code?
Will this be documented?

I'll try to understand better what the new code is doing. And I can
certainly compare with the code from Emacs 23 that works fine for
me.
