推荐答案
启用SSL时的端口号....
将其更改为此[用于发送SSL邮件]:-
There is a problem with the Port No when SSL is enabled....
Change it to this [For sending SSL mails] :-
using System;
using System.Net.Mail;
using System.Web;
//using System.Web.Mail;
using System.Web.Security;
using System.Net.Mail;
using System.Configuration;using System.Net.Mail;
using System.Configuration;
namespace MvcApplication3.Managers
{
public class EmailManager
{
private const string EmailFrom = "user@gmail.com";
public static void SendConfirmationEmail(string userName)
{
var user = Membership.GetUser(userName.ToString());
var confirmationGuid = user.ProviderUserKey.ToString();
var verifyUrl = HttpContext.Current.Request.Url.GetLeftPart
(UriPartial.Authority) + "/Account/Verify/" + confirmationGuid;
using (SmtpClient client = new SmtpClient())
{
using (var message = new MailMessage(EmailFrom, user.Email))
{
message.Subject = "Please Verify your Account";
message.Body = "<html><head><meta content=\"text/html; charset=utf-8\" /></head><body><p>Dear " + user.UserName +
", </p><p>To verify your account, please click the following link:</p>"
+ "<p><a href="\""" verifyurl="" target="\"_blank\"">" + verifyUrl
+ "</a></p><div>Best regards,</div><div>Someone</div><p>Do not forward "
+ "this email. The verify link is private.</p></body></html>";
message.IsBodyHtml = true;
client.Port = 465;
client.EnableSsl = true;
// client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.Send(message);
};
};
}
}
}
将其更改为[用于发送TLS/STARTTLS/非SSL邮件]:-
Change it to this [For sending TLS/ STARTTLS/ non SSL mails] :-
using System;
using System.Net.Mail;
using System.Web;
//using System.Web.Mail;
using System.Web.Security;
using System.Net.Mail;
using System.Configuration;using System.Net.Mail;
using System.Configuration;
namespace MvcApplication3.Managers
{
public class EmailManager
{
private const string EmailFrom = "user@gmail.com";
public static void SendConfirmationEmail(string userName)
{
var user = Membership.GetUser(userName.ToString());
var confirmationGuid = user.ProviderUserKey.ToString();
var verifyUrl = HttpContext.Current.Request.Url.GetLeftPart
(UriPartial.Authority) + "/Account/Verify/" + confirmationGuid;
using (SmtpClient client = new SmtpClient())
{
using (var message = new MailMessage(EmailFrom, user.Email))
{
message.Subject = "Please Verify your Account";
message.Body = "<html><head><meta content=\"text/html; charset=utf-8\" /></head><body><p>Dear " + user.UserName +
", </p><p>To verify your account, please click the following link:</p>"
+ "<p><a href="\""" verifyurl="" target="\"_blank\"">" + verifyUrl
+ "</a></p><div>Best regards,</div><div>Someone</div><p>Do not forward "
+ "this email. The verify link is private.</p></body></html>";
message.IsBodyHtml = true;
client.Port = 587;
client.EnableSsl = false;
// client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.Send(message);
};
};
}
}
}
