When using rdr, you need to make sure that the packets also pass based on
your other rules.

Also, don't use "from any" but use your own network. You don't want to
redirect for outside incoming to port 25. (Use "from $int_net".)

And you don't need the final "port 25".

Also do you have sysctl net.inet.ip.forwarding set to 1 (in
/etc/sysctl.conf, for example).

What do your filter stats and counters show?
