Hi everyone,
I need your help cause I've problems sending certified mail with mono
and a specific provider.
I tried with gmail as explained in
<http://www.mono-project.com/FAQ:_Security#Does_SSL_works_for_SMTP.2C_like_GMail_.3F>http://www.mono-project.com/FAQ:_Security#Does_SSL_works_for_SMTP.2C_like_GMail_.3F
and it works.
Using same code with another local email provider also works.
Using same code with a third email provider in windows I have to
manually install the CA certificate, if I do that in local computer
store I'm able to send certified mails.
In mono I installed the CA certificate using
certmgr --add -c -m CA /tmp/certca.crt
but sending mails I receive the following error, if I launch
certmgr -list -c -m CA
I see the gmail certificate and my new certificate, what I'm doing wrong?
Here is the error.
System.Net.Mail.SmtpException: Message could not be sent. --->
