Whats the complete error message ???

This is complete error
"failure sending mail"

JoCodes 9-Dec-13 2:23am

Add an open port number inside the webconfig settings and check.

If that also is not working then the firewall might be blocking it.

i have give port num and check firewall now error is "Mailbox unavailable. The server response was: This is a submission only port. You must authenticate before sending mail"

JoCodes 9-Dec-13 3:32am

Whats the port number you have tried? The port should be enabled .

JoCodes 9-Dec-13 3:35am

Or try with 587 port number

fak_farrukh 10-Dec-13 3:53am

i have given 587 port number but now error is Mailbox unavailable. The server response was: This is a submission only port. You must authenticate before sending mail

JoCodes 11-Dec-13 0:35am

Do you have any port enabled which can be used?

fak_farrukh 11-Dec-13 2:26am

No i have used both port 25,587 but error still remain.
port 25 error fail sending mail
port 587 error Mailbox unavailable. The server response was: This is a submission only port. You must authenticate before sending mail

Solution 1

Is your mail server using SSL Certificate? If no then try removing the enableSSL=true from the web.config file

Try using a port number which is open inside the webconfig seetings like

<network host="smtp.mail.logicalkey.com" port="25" username="contact@logicalkeys.com" password="acbgtsd" enablessl="true" />

Port number should be changed as per your settings

If still the problem persists check your firewall settings
