Markus is not correct. Actually, when you send mail to an smtp server you are not using port 25 on your computer. You are using any available port to send but you are CONNECTING to listening port 25 at the destination. It is very common for companies to block ANY incoming connections (and, perhaps ISPs also) to prevent a rogue computer from connecting to you, while allowing you to connect OUTBOUND to any server that will accept you. Interestingly, when you are in such a situation, the router will frequently allow incoming connections to you IF you set the port command thru FTP on port 21. However, if you are connecting to an FTP server which is operating on an odd port, the router is not smart enough to allow you to port. In such cases, you must PASV so that the FTP server will allow you to retreive the file, rather than it sending to you on your own data port. With SMTP it is even more common to have port 25 blocked, so as to decrease spam thru open relays. In this case the most logical answer is that your ISP has block incoming port 25 connections to its customers to prevent inadvertant open relays. If this is the case, there is NOTHING you can do in the Sambar settings to overcome this.
