/var/spool/mqueue holds stuff already processed by MailScanner and 
waiting to go out (or be delivered locally)

This says (to me) that 10.1.1.22, who was *supposed* to receive that 
e-mail, isn't accepting connections - or dropping them or something.

Try ssh'ing into that CentOS box, then telnet'ing to the M Sexchange 
server's port 25 like:

$ telnet 10.1.1.22 25
you should get:

220 Blablahblah Microsoft blahblah vulnerable blahblah if it weren't for 
MailScanner I'd be !%#!&%# blah blah version xxx.xxx

If you don't, your M Sexchange server could have a problem with its SMTP 
process being broken/down/hung/etc. - you should look into restarting 
all M Sexchange-related processes just to be on the safe side, I think.
