OS 5.0.5: MMDF has stopped accepting SMTP requests from local lan clients

This was working for years, AFAIK no config changes recently made. My mail
domain is hosted on my OS 5.0.5 box, madonna.gensoftdes.com. Users
send/receive mail from Windows desktops via Outlook Express -- until a few
days ago, when they started getting messages like

550 (NAUTH) Bad authorization: sender '@anne:duck@gensoftdes.com' not
authorized to send to address 'addressee@domain.com'

Local delivery is working for PC users. SMTP delivery is working for users
logged onto madonna.

Turning on level=FTR for smtp, I get the following in chan.log in response
to a test attempt. I can see that the machine named "anne" (the PC from
which the test email originates) is not being successfully resolved as
'anne.gensoftdes.com.' Unfortunately, I have no comparable trace from when
it was working, so don't know how it's supposed to go differently, or what
to make of the messages I see. Here's the contents of chan.log:

I was thinking this needs entries for the other local machines such as
'anne', but it never had them before ....? Anyway, tried:

    local:
    madonna.gensoftdes.com,anne.gensoftdes.com

and also

    local:
    madonna.gensoftdes.com:
    anne.gensoftdes.com:

(the peculiar syntax shown in TA104596) -- both no help.
