yahoo mail rejected

[Glenn Steen]

Two things seem to happen there:
The recipient address has a domain part that is unknown to the server
generating the rejection.

The NDN get seriously mangled (and rightly so, it seems) by a mailscanner
server (perhaps yours),  making it a bit harder to read;-)

Root cause is likely some really bad editing of a "hyperlink email address"
in the senders piece of crap MUA... Tell the sender to actually type the
adress, and it'll likely work much better;-)

Cheers

Hi Everyone,

We're using MailScanner for years already, unfortunately there are
some odd things happening from time to time, here is one instance. One
of our client is trying to send an email using yahoo mail
unfortunately our Postfix-MailScanner server rejected the email and
spewed this error message:

From: System Administrator
Sent: Tuesday, June 07, 2011 11:10 AM
To: Jane Doe
Cc: 'MailScanner has detected a possible fraud attempt from
"us.mc768.mail.yahoo.com" claiming to be MailScanner has detected a
possible fraud attempt from "us.mc768.mail.yahoo.com" claiming to be

The following recipient(s) cannot be reached:

Googling for similar issues led me to none, any ideas why?

Thanks in advance.
