Thanks for answering

O.K., I went through the prompts. It looks as if auth-source-search
didn't find the relevant entry in ~/.authinfo. Instead, it grabbed the
new values entered at the prompt. Moreover, despite the fact that the
same values are present in .authinfo, auth-source asks whether I want to
create a new, encrypted authinfo.gpg.

O.K., I created an ~/.authinfo file (not .authinfo.gpg) with the values
above.

When evaluating the above, auth-source-search does not find the values
in .authinfo and instead prompts for for user name, protocol, and
password. (Note the "Add to file line" below.)

When I create an ~/authinfo.gpg file with exactly the same line,
everything seems to work. I.e., I get the same results as yours below.

In short, auth-source-search finds the correct values in authinfo.gpg
but does not find them in an unencrypted authinfo file with identical
lines. (Note, when running the tests, I deleted .authinfo when trying
.authinfo.gpg and vice versa.)

The value of auth-sources is ("~/.authinfo.gpg" "~/.authinfo").

BTW, authentication with an unencrypted .authinfo file works for nntp.

On a related note, I would gladly switch to .authinfo.gpp, except that I
find I am asked for my encryption password three times during startup:
once for imap and once for each nntp server.

Thanks,
Matt
