Sending email from classic ASP - asp-classic

SOLVED: Two students gave us the wrong emails, and for some reason the script refused to process more if it encountered a wrong email. I am still wondering why is it so !
I am trying to read a bunch of records from a database, and for each record I am creating some text based on some fields of the record and then sending them as email to the email address provided in the record.
The problem is the email gets sent for only about 5-10 records (it varies, once it sent 5 emails, with cc and everything, next day it sent 7).
After this it comes up with the famous error:
error '8004020f'
/sendEmail.asp, line 139
I have researched all around the internet, and I see many have issues with this error, but not the kind that I am having, in which few emails are send and then it stops.
Also, all emails are being sent to the same domain, the official school email of the students.
Any ideas? Any settings that I might want to ask the website hosting guy to change?
Here is the code.
Dim objMail
Set objMail = CreateObject("CDO.Message")
objMail.From= "someEmail"
objMail.To=rstemp("Email")
objMail.Cc = "someEmail"
objMail.Subject = subjecttext
objMail.HTMLBody=tempData
objMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendusing")= 2
'Name or IP of remote SMTP server
objMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserver")="smtp.*"
'Server port
objMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserverport")=25
objMail.Configuration.Fields.Update
objMail.Send
set objMail=nothing
tempData = nothing
EDIT: On more debugging, it turns out that when I replace the objMail.To from sending it to each student's email to my own email. It works fine and sends all the emails to me.

Please check first all the Emails is valid and no test email is there. and you can test it with send all emails on same email address for no. of time and can track the problem that is this Email address problem or something else.

Not able to send Email messages in WordPress

Tried many times but no luck... I don't where the problem. Required help in solving the above code.
//SEND MAIL
$mymail=file_get_contents("mailaddress.txt");
$frommail=file_get_contents('CCmail.txt');
$to = $mymail;
$subject = "User details";
$txt = "<b>USER DETAILS</b>\r\n\r\nName: $fname\r\nEmail: $email\r\nContact no: $mobile\r\nProvince: $city $state\r\n Gender: $gender\r\nComment: $comment\r\n\r\n<b>QUESTION & ANSWERS</b>\r\n\r\nGender: $selectedgender\r\nSleeping Hours: $sleep\r\nWorking Hours: $work\r\nWeight & Height: $weightheight\r\nIllness: $illness\r\nAllergies: $allergies\r\nSweating: $sweating\r\nAge: $age\r\nSpecial Care: $care\r\nSleeping Position: $sleepingposition\r\nLevel Of Comfort: $comfort\r\nPreference: $preference\r\n";
$headers = "From: $frommail" . "\r\n" .
"CC: $frommail";
wp_mail($to,$subject,$txt,$headers);
echo"successfull";
}
}
else{
echo"Not Allowed";
}
?>
For WordPress (or indeed for any software) to send email messages it needs to have access to a Simple Mail Transfer Protocol (SMTP) server somewhere on the Internet.
The best way to do this is to
install a WordPress plugin like WP Mail SMTP. It takes over from php's rudimentary built-in SMTP handler. It also provides a plugin settings screen where you can configure your email settings.
get yourself an account on one of the SMTP services mentioned in the plugin's documentation. I like sendgrid.com for this purpose, because it has a free tier allowing up to 100 messages a day forever.
You could use the SMTP server belonging to your own email provider. But the big providers like gmail and yahoo really don't like automated email systems sending email through them, and they may refuse connections from your WordPress instance. They especially don't like incorrectly formatted email messages: the kind you might send while debugging your application. They're trying to resist attacks from spammers and cybercreeps.
Write and test your code sending only to email accounts under your control (avoiding developer spam to unsuspecting people).
A word to the wise: many countries prohibit "protected health information" -- data about medical patients -- in email messages. It's impossible to guarantee the confidentiality of email due to the way it works.
In the USA it's even illegal for a hospital or doctor to send ANY email to a patient without that patient's consent: the From: and To: fields of the email identify the recipient as a patient of the sender. Respect your patients' confidentiality!

CDO.Message To and From Fields Changed to "Friendly Name" and Email Address

When I first created this Classic ASP script, with the help of W3Schools, to send email, it worked fine. Now I'm having issues with sending the actual email; it appears to hang on the .Send method.
I noticed that when I set the To and From email address to just the email address, it reformats it to a "Friendly Name"/Email Address format:
myMail.From="Support#myDomain.com"
Response.Write myMail.From
The output of the Response Write is:
"Support#myDomain.com" <Support#myDomain.com>
I don't know if this was happening before, or if I should be setting the To and From fields in this format. Just to check if this is causing my problem, is there anyway to prevent these fields from being changed from just the email address?
Maybe the e-mail sending from the server now needs some kind of authentication such as setting these fields:
' Outgoing SMTP server.
objCDO.Configuration.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "mail.mydomain.com"
objCDO.Configuration.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
objCDO.Configuration.Fields("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objCDO.Configuration.Fields("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60
' Type of authentication, 0=NONE, 1-Basic (Base64 encoded), and 2=NTLM.
objCDO.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
' UserID on the SMTP server
objCDO.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = "support#mydomain.com"
' Password on the SMTP server
objCDO.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "myemailpassword"
' Update config.
objCDO.Configuration.Fields.Update
The issue stemmed from the fact that the "From" email address was actually a distribution list and the account credentials used to login to the email server were not authorized to "Send As". Once that was rectified emails sent without further problems.
Thanks for the response.

Email Address Varification Application in ASP.NET

I am getting 555 syntax error in mailfrom
SendData(tcpSocket, string.Format("MAIL From: {0}\r\n", MailFrom));
if (!CheckResponse(tcpSocket, 220))
{
tcpSocket.Close();
return false;
}
is it the problem in my local system because of localhost?
Please help me. I am using this code from below link.
http://www.codeproject.com/Articles/5189/End-to-end-Email-Address-Verification-for-Applicat
Please don't try to implement your own SMTP client, use the one that comes with .NET: System.Net.Mail.SmtpClient.
Many SMTP servers require TLS, for example, which your code does not account for.
Furthermore, for security reasons most mailservers will not reveal if an email address in an RCPT TO line is valid or not. If a system can positively reveal an address exists then it can be used by spam harvesters. Consequently using a dry-run of an SMTP client should only be used to validate an email address (because of the complicated rules regarding valid email addresses). The verification (a separate concept from validation) must be performed manually by requiring the user to respond to an email sent to that address, there is no other way to be sure.

Email goes to spam instead of inbox

We have a domain name "www.mycloudcctv.com" at godaddy.com and we have created a sub domain cam.mycloudcctv.com which points to 212.78.237.157
We have an application running on third party server (212.78.237.157). This application wants to send an email on our behalf using the email address “alerts# mycloudcctv.com ". Following code snippet (ASP.NET) is being used to send the email from (212.78.237.157)
var mailClient = new SmtpClient();
mailClient.Credentials = new NetworkCredential { UserName = "alerts#mycloudcctv.com", Password = "xyz" };
mailClient.Port = 25;
mailClient.Host = "smtpout.secureserver.net";
mailClient.EnableSsl = false;
var mail = new MailMessage("alerts#mycloudcctv.com", "azharmalik3#hotmail.com", "Test Smtp server", "Testing mycloudcctv server") { IsBodyHtml = true };
//Now Send the message
mailClient.Send(mail);
Everything works fine and emails are being sent however they end up in SPAM/JUNK folders of gmail/hotmail/yahoo. Could you please provide us necessary information so that our emails go to inbox instead of spam folders?
this is a BIG question with lots of complex issues, but it really boils down to three main areas:
Does the email come from a server which has be delegated the authority to deliver emails for the specified domain?
Is the content of the email just hyperlinks and does it contain text which would trigger spam assassin to mark as spam.
Is your server blacklisted for spam
For point 1 look into how to setup SPF records for send authority. http://www.mydigitallife.info/how-to-set-up-and-create-sender-policy-framework-spf-domain-dns-txt-record-with-wizard/
For point 2 get a copy of spam assassin and run your emails through it to see the score.
http://spamassassin.apache.org/
For point 3 http://whatismyipaddress.com/blacklist-check
This is not that easy. There are fair few things you have to do. For example SendGrid has some guidelines:

I found this blog-posting extremely useful! Give it a good read, it covers a lot of the points already mentioned here thus far:

Email sent from web server causes gmail to treat as phishing. How to get rid of this?

I am sending account activation email from my .net app.
I set the from address to "xyz.support#gmail.com" and from name "xyz" where xyz is the name of the domain i.e. our website.
It was not a problem when we were using Google's SMTP server as I provided credentials to google during sending. But now I am using my own web server's SMTP to send the email.
When I view the activation email in gmail, I get this:
This message may not have been sent by: xyz.support#gmail.com Learn more Report phishing
Is there a way to get rid of this so that gmail and other client don't show this message?
Here is the code:
var smtpClient = new SmtpClient();
var message = new MailMessage();
smtpClient.Host = _config.SMTPServer;
message.From = new MailAddress("xyz.support#gmail.com", "xyz");
message.To.Add("newuser#gmail.com");
message.IsBodyHtml = true;
message.Subject = "Test subject";
message.Body = "Test Body";
smtpClient.Send(message);
Thanks
The domain of the FROM address has to match the domain of the SMTP server that is sending the email, otherwise your message is treated as as spam.
This explains why you avoid the "error" by sending via Google's SMTP server.
The suggestion by IrishChieftain to use SPF helped me, so here is a summary of the steps I did:
1.) First, I also received emails in my GMail inbox that I sent from my sever and that got the "This message may not have been sent by..." warning.
2.) Next, I looked at the source of the email inside GMail (clicke the arrow next to the message and select "Display original"). An excerpt from there was:
Received-SPF: fail (google.com: domain of me#mydomain.com does not
designate 211.113.37.19 as permitted sender) client-ip=211.113.37.19;
So Google directly told me what to do: Add some SPF records in the DNS of my domain "mydomain.com" to get rid of this warning.
3.) Therefore I logged into the control panel of my DNS provider and added two TXT records, something like this:
*.mydomain.com. 180 v=spf1 +a +mx ip4:211.113.37.19 -all
mydomain.com. 180 v=spf1 +a +mx ip4:211.113.37.19 -all
Please note that I entered each line in three separate fields:
One field for *.mydomain.com.
One field for 180 (the TTL, 3 minutes in my example)
One field for v=spf1 +a +mx ip4:211.113.37.19 -all
4.) After that, I waited some time and tried to resend. This succeeded. Google now shows in the original:
Received-SPF: pass (google.com: domain of Received-SPF: pass (google.com: domain of me#mydomain.com designates 211.113.37.19 as permitted sender) client-ip=211.113.37.19;
Please note that I choose the SPF version since the mail server is on a different machine as the web server, so I could not perform the other solution as Mulmot wrote.
There is also an SPF Wizard from Microsoft to correctly generate SPF records. Alternatively, here is yet another SPF generator.
