Ok,  i don't know Postfix so someone else might have to pick up here.

It sounds like there might be a local mailer (submission queue) running 
on X, but not SMTP. The message from A was that it couldn't connect to 
X. (Deferred: Connection timed out with tools2.wms.cell.com)

what do you get if you try telnetting from A to X
telnet tools2.wms.cell.com 25

(if you get a connection, good, try following these instructions to send 
a mail manually via telnet)   http://www.yuki-onna.co.uk/email/smtp.html

If not, have you tried restarting postfix on X?

Paul.
