Try to specify port number and especially SSL, for instance, they're
required for Gmail at least.

I can not install the SSL certificate, but normally without this certificate
should each email?

well what happens if username or password is blank? i'd reccomend
always authenticating.

I've been stuck in the same boat and 'always authenticating' seems to
work for me.

The Reponse Server : 530 5.7.3

You won't install nothing, you just pass SSL parameter if target mail
server requires SSL authentication like Gmail.

So try to set "enableSSL" boolean value to true and try again:

Hello,

i have configure one server with windows 2003 and i have configure the
server SMTP.

Does that mean you are sending the email to this SMTP server? Or are you sending
them to the Exchange server that Outlook is using?

If it is the SMTP server, it is probably just depositing them in a Drop folder,
unless you have configured it to relay them somewhere.

 

[Scottmat]

My problem is solved, it was necessary to check TLS encryption

No, I use my SMTP server as a relay.

Thank you all
