That looks to me that your client is not finding the authenication
data for your smarthost in /etc/exim4/passwd.client. This might be a
duplicate of #244724.

Remedies are either using "*" as a host name, or to list all possible
reverse host names for smtp.umn.edu, namely smtp-m.tc.umn.edu,
smtp-c.tc.umn.edu, and smtp-w.tc.umn.edu in passwd.client, each of
them in its dedicated line.

Now, to explain the "it has worked until recently": Is it possible
that the three IP addresses that smtp.umn.edu points to have been
reverse resolving to smtp.umn.edu until recently, when the smtp-x host
names have been introduced?

Greetings
Marc
