Sorry, I probably didn't say that right. What I meant was, if it tries to
reverse lookup a name based its own IP, it wouldn't work. If that matters. I
do see it complaining things like 'gethostbyaddr(192.168.1.103) failed: 1'.

Yes. Do I need to restart anything after changing hosts? (I haven't used
Windows in years, but I still get this feeling that I should reboot after
making any change...)

Yes, for example:
Nov 17 19:52:53 bifrost sm-mta: iAI3qqvn001740: ruleset=check_rcpt,
arg1=<charon at seektruth.org>, relay=mxout2.cac.washington.edu [188.8.131.52],
reject=550 5.7.1 <charon at seektruth.org>... Relaying denied
Is it denying mail because it thinks it's not seektruth.org?
