postfix shouldn't be affected by a hostname change but you can check
mydestination, myhostname, and myorigin in "/etc/postfix/main.cf",
just in case, as well as whatever virtual settings that you're using
to host email for more than one domain (I've never done that so I
don't know what settings to look for).
I'd check the configuration of cyrus or dovecot (whichever you're
using) for your problem because it (whichever it is) must be the
source of your problem.
