Cannot receive email from specific address

Hey all,
 I have a customer who is routing incoming mail through softscan (managed spam solution) which for some reason is unable to deliver mail from one specific email address to their Exchange 2000 mail server, fails to deliver the mail with the following error:
reason: "IP" failed after I sent the message. Remote host said: 554 Transaction failed

Other email addresses from the same sender domain get through fine, just this particular email address. When I try to send a test mail spoofing this email address through telnet I get the following error:

554 Unable to process message: msg.1195215309.247295.4273 - error: Illegal breakage found in header: <Test_>

If I try the same test without putting any data in the mail it gets queued for delivery. Has anyone come across this error before? Incidentally I get this same error when I try putting any data regardless of the sender email address. Thanks in advance.

I've never seen this before, but if it happens for only one email address, it might be possible that there's something wrong with the format of the address (like a non-ascii character, or an apostrophe).  There are some exaples here:

Nope, there is nothing malformed in the sender email address, interestingly when I send a blank email (just a period after specifing data) it gets queued for delivery. I'm beginning to think it's softscan doing something bizarre. Example below:

250-dkcphmx58.softcom.dk Hi host1-2-3-4.in-addr.btopenworld.com [1.2.3.4]
250-PIPELINING
250-8BITMIME
250 STARTTLS
mail from:support@domain.com
250 <support@domain.com>, sender OK
rcpt to:another@domain2.com
250 <another@domain2.com>, recipient ok
data
354 go ahead
Test
.
554 Unable to process message: msg.1195220520.635620.11870 - error: Illegal brea
kage found in header: <Test_>

Ah well, it was just a thought.  I don't know anything about softscan, I'm afraid.  I wonder if it expects you to supply a complete set of headers at that point?  Mind you, if it does, why only for that one address?

Think I've found it, one of the mail relay servers specified in the NDR has been blacklisted by TQMCUBE. Suspect softscan might be using this RBL.

Still not sure why it thinks I've put a break in the data part though. Bizarre.

Thanks anyway.

I've had the same problem.

I've found though if the first data line is just a carriage return, it works fine.

For example:
354 go ahead
TEST
.
The above will return the illegal breakage line.
However the following works:

354 go ahead

TEST

.

Good luck!
