I'm trying to send email from an ASP.NET site hosted on a Plesk account. I've managed to send email before form an Office 365 account but I am not having any luck. I keep getting the following error:
System.Net.Mail.SmtpException: Server does not support secure connections. at System.Net.Mail.SmtpConnection.GetConnection(ServicePoint servicePoint) at System.Net.Mail.SmtpTransport.GetConnection(ServicePoint servicePoint) at System.Net.Mail.SmtpClient.GetConnection() at System.Net.Mail.SmtpClient.Send(MailMessage message) at PeaceOfMail.Contact.sendEmail()
I've tried using port 25
setting EnableSsl = false
setting Host = smtpout.secureserver.net and host = relay-hosting.secureserver.net
I feel like I'm missing something very basic but I cannot figure out what it is.
Thanks for you help
what happens when you use port 465
