I'd say that your ISP has its 'doze machine misconfigured because it
claims it is "machine.remailer.address" but that name doesn't exist.
The IP of the machine is 206.99.235.25. That system handed the
message to samaria.achilles.net.
The 'doze machine is the remailer which is broken. whois shows

qmail got the message next. Pretty sparse data here. I guess one
would need to be familiar with qmail's operation to know what "invoked
from network" means. Still, it doesn't say what machine or anything.
AFAIK qmail is the smtp program of samaria.achilles.net. It puts the mail into
the users (Brenda's) directory of the pop server program. Both are on same
machine so no
IP addresses are mentionned.

Fetchmail on Brenda's box fetches the mail with POP3 and write its receive
line.
Her .fetchmailrc contains no smtpaddress field, user name is bjb, so it
claims to
fetch for bjb@localhost.
pop1.achilles.net and samaria.achilles.net are the same machine of her ISP.

Nope, it is telling you that your ISP is (partially) messed up :-).
Nope, the remailer is partially messed up.

The purpose of the Received: headers are just to allow admins to track
down what happened to a message so that configs can be debugged. Each
system can be configured to put whatever it wants as a Received:
header, or nothing at all. It is recommended to include the info,
though, in case something goes wrong somewhere.
Advanced users also need Received: headers to track down spammers. Bad luck if
an open relay doesn't log IP addresses of senders.
