Sendmail address resolution problem

[Steven W. Orr]

I have a guy I'm trying to send mail to. He's at a domain called 
alginin.org and he's hosting his domain off his cable modem at home using 
RCN. I too am hosting my domain at home using RCN. We are both running 
linux. He's using Postfix and I'm running sendmail.

If I do a dig I see:

527 > dig alginin.org mx

; <<>> DiG 9.2.5 <<>> alginin.org mx
;; global options:  printcmd

Note that home.alginin.org is resolved to 209.6.219.177

Then if I

telnet 209.6.219.177 25

I see that I'm talking to his Postfix server. All is peachy.

But my mail fails to deliver via sendmail and the problem seems to be that 
sendmail is trying to deliver to the wrong address.

Jun 23 22:31:37 saturn sendmail[9853]: j5O2UaPX009847: 
to=<max at alginin.org>, delay=00:01:01, xdelay=00:01:00, mailer=esmtp, 
pri=230639, relay=home.alginin.org. [209.150.61.19], dsn=4.0.0, 
stat=Deferred: Connection timed out with home.alginin.org.

Note that the 209.150.61.19 is wrong. Why in the Wide World of Sports 
could this possibly be happening? I am verstumped! And where the hell is 
this address coming from?

Anyone? Please?
