In general, I would start debugging mail server (which is supposed to 
send mail passed to it from inside) by doing it in command line. I'm 
pasting my doing it, just obscured machine names (my server is postfix, 
if yours is different, some answers may be somewhat different, though 
they should be to the same effect):

ssh [some user]@[server.in.question]

[valeri@XXXXX ~]$ telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

RCPT To: galtsev@YYYYY.uchicago.edu
250 2.1.5 Ok
DATA
354 End data with <CR><LF>.<CR><LF>
This is anything, just to test
.
250 2.0.0 Ok: queued as 4AFDE1AF391

Once you see this works, /var/log/maillog is next place to read.


I hope, this helps.
