hi, i´m doing a aplication in asp.net 2.0 and i want send an automatic
mail when the users do an operations. i use the library
System.Net.Mail.MailMessage. and I specify all the properties
(to,from,body,host and port). i want send the mail by another port not
from the port 25. Can i do That?. I dont specify credencials.
i configure the server to the port that i want send in the IIS, but its
not works.

System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The
server response was: 5.7.1 Unable to relay....

this is the error.

Can I send the mail by another port that is not the 25?

thks and sorry for my English!
 
I have a complete 2.0 (and 1.1) example at my blog.

You have to match the ports.
Your smtp server has to receive messages on a non standard port ........
If that's the case, then you can specify a different port number.
