When I set the mail I input the information to these areas with a working email in gmail account:
Store Admin Email:
Store Admin Email Display Name:
Host:
Port:
User:
Password:
Enable SSL:
Use default credentials:
I checked "Enable SSL" and leaved "Use default credentials" unchecked.
But it didn't work when I test it. The error message is as the following:
"Request for the permission of type 'System.Net.Mail.SmtpPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."
The only problem I think is "Port" which I got from my gmail account "Setting--Thunderbird--Outgoing SMTP". I also tried the Port 587 from another post. It didn't work either.
What is the problem?
