My issue is pretty simple, and that is my YAF can't send emails...so no registration confirmations, no emails to user groups..not even using the SMTP Test in the install pages.

So, in my app.config file I have:

In my mail.config I have:

If I try to send a registration confirmation, a test email or even a Mail (SMTP) Sending Test it all fails, nothing, nada.

The details I am using (password, host, port etc) are all correct, I know this because I have used the same details when setting up the POP3/SMTP to link the mailbox to my phone, it works.

Checking YAF logs and it says this:

The Mail (SMTP) Sending Test times out as well.

I am running the latest version of YAF (2.1.2) and have restarted the app (using the admin menus within YAF).

I'm close to whits end!

Any help would be great.

try to set it to false...

<add key="YAF.UseSMTPSSL" value="false" />

<add key="YAF.UseSMTPSSL" value="false" />

I can try, but according to the settings:

http://www.zoho.com/mail/help/zoho-smtp.html 

It uses SSL

<add key="YAF.UseSMTPSSL" value="false" />

Still not working!

Solved it!!

It seems that Zoho does not support TLS (latest SSL protocol)....and Microsoft .Net supports only TLS..not SSL (older protocol). Thats why it wont work.

The SmtpClient class only supports the SMTP Service Extension for Secure SMTP over Transport Layer Security as defined in RFC 3207. In this mode, the SMTP session begins on an unencrypted channel, then a STARTTLS command is issued by the client to the server to switch to secure communication using SSL. See RFC 3207 published by the Internet Engineering Task Force (IETF) for more information.

So changing to use port 587 worked.

EDIT

Still doesn't work. It worked when using the test in the install pages, but when registering, and/or sending mail to users it still doesnt work.

Back to square one.

EDIT OF THE EDIT

Got it to work. As above but I had the wrong "From" email in the "Board Settings" page within YAF itself
