In my previous message, if someone wants to test any of the various
Exim versions/builds just relay a message using whatever means thru
their server from <exim-rulez @ test.tymes.net> to <exim-rulez @
test.tymes.net>. You can use any email address @ test.tymes.net as
the mx host isn't configure with any mailboxes and doesn't relay. The
message you are trying to relay can even be blank -- I first noticed
this only because of infected messages but it will work for 550 User
unknowns so the message content isn't even important.
An Exim server should only try to send two messages after which it
should stop -- freezing (or whatever) the first message and the
generated bounce.
Here is a quick list of Exim Mail servers which haven't respected 550
errors and their version number at the time. I stopped looking at 20
different servers. You might understand why I suspect Exim may have
some sort of issue...
82.108.130.24 mail.ncipher.com (Exim 3.34 #1)
203.101.80.60 smtp.instaxs.net (Exim 3.36 #1)

69.72.225.186 bob.xstreamhost.com (Exim 4.50)
The bounces were generated by virus/file rejections, unknown users,
and full mailboxes. The retry times ranged from about 90 minutes to 4
hours. If they were retrying less frequently I probably missed them
as I quickly greped this list. I don't know how many more servers
there may which are causing User Unknown errors as they would probably
be impossible to find.
