User claims 'sent email ends up in recipient's quarantine' . . .

[Steve Conrad]

We have GW 6.5 . . .

A User is claiming that every third or fourth email sent to this other
company is becoming lost . . . in a couple of cases they discovered
the emails in the recipient's server's quarantine — with an explanation of
"Unknown recipient". [However, the "x-gfi-me-to: " address appears
to be correct.]

The Receiving company's email is GFI.

There maybe a blackberry in the mix, so I'm wondering if anyone has
run into any header corruption issues . . . either in replies sent from
a blackberry (through GroupWise) or with how some email systems
may interpret headers from a GroupWise system.

One other possible clue . . . the quarantined info (on their system)
reported the email as:

06/22/2009 01:51 PM 11,372 ***@company.com_Unknown Recipient_no subject_19E923DC.eml

. . . "***@company.com" had our sender's Internet address, but I see the file ends with an .eml
extension. (I don't know if this could mean anything, or not . . . possibly that's only how GFI stored
the quarantined email.)

Any advice would be appreciated!

Thanks,

Steve

Did all of the victim mail have a blank subject? At any rate isn't this
for GFI to look at?

Thanks.

Yes, it seems like that's what they're saying ("Blank subject") . . .
and, I agree, this strikes me as more likely a problem with the
recipient's email server.

But I can think of two scenarios where this might be a problem
on 'our side':

- IF there are any known issues with, let's say, Blackberrys
routing replies through a GroupWise system. [Maybe header
corruption. (Which is why I raised the question on the list.)]

- Or, IF there might be a typo issue. The recipient's email
address began with a letter that should be a lower-case "L"
but might actually have been an upper-case " i ". [In some
fonts this would look the same — and would thoroughly
explain the receiving server's "Unknown recipient". (I thought
of this possibility, afterwards, but haven't been able to prove
anything up-to-this-point.)]

Has there been any cases of Header corruption involving
Blackberry (or another device)'s use. [I'm not sure if the User
has a Blackberry . . . it might even be an iPhone.]
