As I said, you obviously do not understand how smtp works. This is made 
obvious by your questions, and failure to understand that port 25 is 
*the* port for receiving email on the public internet. Period.

If your main problem with port 25 is *sending* (relaying outbound) 
mails, then you will need to take this up with your ISP. If they are 
unable or unwilling to address the problem, one option would be to setup 
your system to relay through some other smtp relay service on the 
internet using port 587 as you apparently read somwehere, but you don't 
do this by changing the main smtpd daemon to port 587, because as you 
discovered, you won't be able to receive *any* emails like this.

That said, I fail to see any relevance to dovecot in this thread...
