Sounds like you need an access list on your rtr to permit traffic in bound to your mail server
access-list 110 remark Allow Outside Access to Mail Svr
acc 110 permit tcp 0.0.0.0 255.255.255.255 your.mail.ser.ver 0.0.0.0 eq 25 log
access-list 110 deny tcp any any
apply this on your external interface
config t
int e0
access-group 110 in
exit
wr mem
