Sounds like they may have gotten hit with a virus or pissed someone off.
I would block the domain from relaying & inform the customer, possibly
make them change their email account passwords if it's not a large
organization. Ask them to relay through their provider if possible for
the time being. Fail2ban would be the best solution for the time being
as previously mentioned.

IE, it looks like you cleansed the domain portion, but, in the log,
are the
all, or most, of the e-mails legitimate?
I've seen this with random attempts at guessing e-mails and
passwords, but
not with all legit e-mails.
If they are all legit, is the domain yours? Or is it theirs? (IE do
you
host it as an ISP, or is this the only domain and you control it?)

Hi Michael,
they are all legitimate email addresses, for one domain only though.
We host it as an ISP.
Thanks!
