How do you "redirect" port 2525 to 25? With a firewall rule?
You can use Exim's daemon_smtp_ports option to make it listen on more
than one port.

There's nothing fundamental in Exim that does this. What version of Exim
do you have? Assuming v4, check your ACLs. Post your config somewhere if
you're still having trouble. The command "exim -bh X.X.X.X" where
X.X.X.X is the source IP (possibly in conjunction with the -oMi option)
can be handy here. See the docs for more details.

My best guess is that the source IP is getting translated by whatever
means you're using to "redirect" the port along the way.
