Help - Mail Delivery System Error

[Xeserve]

Whenever I try to respond to a ticket the following is made as a response:

This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: [email of client] unrouteable mail domain "gmail.com" ------ This is a copy of the message, including all the headers. ------ Return-path: Received: from nobody by [server hostname] with local (Exim 4.52) id 1Fp6p1-0004SM-Ni for [email of client]; Sat, 10 Jun 2006 13:00:27 -0400 To: [email of client]Subject: [#PRV-617651]: help me solve this issue X-Mailer: Kayako eSupport v3.00.80 X-Priority: 3 MIME-Version: 1.0 Date: Sat, 10 Jun 2006 13:00:27 -0400 Message-ID: Cc: From: "Xeserve" Reply-To: [email sending from] Content-Type: multipart/alternative; boundary="=_608fa13bf217c35f00e56088532a6867" --=_608fa13bf217c35f00e56088532a6867 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 8bit [text that was made as a response in esupport] Ticket Details =================== Ticket ID: PRV-617651 Department: General Priority: Medium Status: Open --=_608fa13bf217c35f00e56088532a6867 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: none [text that was made as a response in esupport]

Please be aware that I already have a ticket open with kayako but as usual, I never get a response or they take their time because their support sucks so if anybody has any ideas I'd be glad to listen.
