CyRius Posted February 20, 2010 Share Posted February 20, 2010 (edited) Im creating an smtp (and a pop3) server, but i am stucked.SMTP servers usually listening on the port 25, right? But there are exceptions like gmail (465).Lets say my server receives an email from the client with a recipient <firstname.lastname@example.org>. How could the server decide which port to use to connect to the recipient's smtp server? And how to decide which IP to connect (gmail.com is different than smtp.gmail.com). And how to decide to use SSL/TLS authentication or not?Greetz, CyRius Edited February 20, 2010 by CyRius [font="Courier New"][size="3"]CyRius Developments[/size][/font][list][*]CO Proxy[*]CO Assembly tool[*]CO PacketSniffer[*]Larkinor proxy[*]BoIM Messenger[*]Encrypt/Decrypt[*]Hashtables[*]Slowest, but greatest skins ever xD[/list] Link to comment Share on other sites More sharing options...
