Hello,
I noticed a frozen bounce in our mail queue for a message which seems to
have come from (envelope sender)
'4526433.tHjd3LnMP.@pcrm.unikorea.go.kr'.
As far as I can tell, the '.@' part of the address is invalid according
to RFC2822. So why did exim accept it if it is syntactically invalid?
The message passed through our mailhub and onto an Exchange server,
which rejected the address and caused the bounce to go back out. The
Exchange server gave the error: 501 5.1.7 Invalid address.
We are using exim 4.69.
Thanks,
John.
