cd /usr/port/mail/postfix
make deinstall reinstall

Here follows my interpretation of the problem: The aborting error
occurs in work/postfix-2.9.1/src/util/myaddrinfo.c, function
sockaddr_to_hostaddr. The function is called with an AF_INET6 address
and reaches the getnameinfo call at the end. getnameinfo
returns EAI_FAMILY. (getnameinfo should be able to process AF_INET6
addresses. No idea why it refuses to do so.)

The kernel is compiled including INET6 but IPv6 is not used on the
machine (/etc/make.conf: WITHOUT_IPV6=yes). Some lines from the kernel
configuration:
> cpu             I686_CPU
> ident           EICHE
> options         SCHED_ULE               # ULE scheduler
> options         PREEMPTION              # Enable kernel thread preemption
> options         INET                    # InterNETworking
> options         INET6                   # IPv6 communications protocols
> options         FFS                     # Berkeley Fast Filesystem
> options         SOFTUPDATES             # Enable FFS soft updates

>Fix:
I was able to compile and install the port for my non-IPv6 machine after
changing the port Makefile, adding -DNO_IPV6 to the
POSTFIX_CCARGS.
