You can put any command in post-up or if you prefer you can add a script
in /etc/network/if-up.d such this one:
$ cat /etc/network/if-up.d/postfix
#! /bin/sh
# update postfix copy of resolv.conf (picked up automatically); only default instance is handled
[ lo != "$IFACE" ] && cp -pLu /etc/resolv.conf /var/spool/postfix/etc/resolv.conf 2>/dev/null || :
