This is not only a pfSense problem. You'll have to look very hard to
find a firewall that is capable of doing NAT reflection.
If you're using the DNS forwarder on pfSense, you could just add entries
to it, that point for this name to another IP.

I have port forwarding set up on my pfsense box to acess an imap-server
on the network connected to my LAN interface. Everything works well when
I'm using it from the outside:
[EMAIL PROTECTED]:~$ telnet mail.example.com 143
Trying 1.2.3.4...
Connected to pfsense.example.com.
Escape character is '^]'.
* OK Dovecot ready.
However some of my applications running on machines on the internal
network need to access the imap server using the outside hostname and
this does not work. pfSense does not seem to understand that traffic
with the destination address of the WAN interface originating from the
network connected to the LAN interface should be port forwarded in the
same way as connections from the outside.
What is the *right* way to solve this? Right now i just use an entry in
the hosts file to make the connections go directly to the internal ip
but that's not the solution I'm looking for.
